Latterly Joseph went into partnership with two of his sons and is thought to have retired to London in 1862. His son, John Joshua Sewill (d. 1891) succeeded him and headed the business until his death in 1891, The firm was well regarded and opened branches in London (at 30 Cornhill prior to 1882), Glasgow and Locle (Switzerland). In 1867 a chronometer by Sewill won the Greenwich Trials and they became makers to the Admiralty. In the 1874 Greenwich Trials their chronometers came first and third. They also entered pieces into Kew trials, where a karrusel watch was awarded 81.8 marks in 1900. They won an award for 'services to horology' at the Paris Exhibition of 1862, and later became 'Maker to the Queen of Spain'.Condition Report: Tube is filled with no obvious airlocks, the float mechanism etc is intact and operational however will require setting-up/calibration.

The firm became one of the most prolific makers of scientific instruments and continued trading well into the 20th century.The current lot is a textbook example of a Fishery or Sea Coast storm barometer devised by Admiral Robert Fitzroy in the 1860`s to aid mariners in the forecasting of storms. Fitzroy lobbied the Board of Trade resulting in this type of barometer being supplied (at public expense) to many coastal communities for display in a prominent public space. In addition to this The Royal Lifeboat Institution installed these barometers into each of its stations and the Duke of Northumberland (in association with the British Meteorological Society) erected several on the coast of Northumberland. By 1864 over 80 barometers had been installed by the Board of Trade and a further 14 by the Duke of Northumberland with their usefulness fully appreciated in Fitzroy's Meteorological Office Report published that year.Condition Report: The tube is filled with no apparent airlocks and both Vernier slides are fully operational however there is only one key present. The arched signature plate has some slight hairline cracking to the lower right hand corner which can only really be seen on very close examination being behind the bevel cut of the glass. The thermometer is in good condition although the tube is probably a replacement. The case is in good original condition with only minor bumps, scuffs and other age related blemishes. Condition Report Disclaimer

The firm became one of the most prolific makers of scientific instruments and continued trading well into the 20th century.The current lot is made to the principles laid down by Nicholas Fortin (1750-1831) and incorporates a glazed cistern so that the level can be calibrated via the adjustment screw to the base against an inverted conical ivory cone in the cistern in order to obtain consistency in the readings. This particular type of barometer provides an accurate reading hence was generally adopted for laboratory use throughout the 19th and early 20th centuries.Condition Report: Instrument is filled with mercury and provides a good reading with no apparent airlocks. The silvering to the scales is in good condition with only minor discolouration/mellowing and the Vernier slide is operational. The brass case is in good condition although has probably been polished at some point (original lacquer removed) and the finish is generally a little dull/oxidised. The cabinet no longer has its original clasp for the door (has been substituted for a pivoted hook clasp) and has some noticeable bumps and scuffs to the exterior otherwise is in sound original condition. Condition Report Disclaimer

AN IMPRESSIVE INLAID MAHOGANY EIGHT-DAY QUARTER CHIMING LONGCASE CLOCK WITH MOONPHASEThe dial bearing a signature for Robert Roskill, Liverpool, circa 1900 incorporating earlier elementsThe substantial five columnar pillar triple train movement with plates measuring 9 by 11 inches and deadbeat escapement regulated by seconds pendulum, the chiming train incorporating a choice of two sets of notations for the quarters sounding via transverse pinned cylinder on eight tubular gongs suspended from the case backboard and the hour train sounding on an additional larger gong, the 14 inch brass break-arch dial with subsidiary seconds dial and bearing inscription Robert Roskill, Liverpool to the foliate scroll engraved silvered centre within applied Roman numeral chapter ring with scroll and sceptre half hour markers and Arabic five minutes to outer track, with pierced blued steel hands, mask inhabited scroll cast spandrels to angles and strike/silent opposing chime selection levers to margins, the arch with rolling moonphase incorporating terrestrial globe engraved silvered lunettes and age of the moon scale to the upper margin, in a case in the manner of Gillows with cavetto moulded swan neck pediment, gilt pagoda and wheatsheaf floral decorated panel inserts and break-arch frieze over the hinged glazed dial aperture applied with reeded Roman Doric half-columns to stiles and flanked by conforming complete free standing columns, the sides each with lozenge panel inlaid frieze over rectangular brass grille sound fret and conforming pilaster planted next to bargeboards at the rear, the trunk with concave throat and alternating lozenge and shaped diamond panel inlaid frieze over shaped-top caddy-moulded door veneered with an oval flame figured panel within line border and quartered infill, flanked by free-standing columns to angles and with small rectangular panel beneath, the sides each inlaid with an arrangement of oval circular panels within triple line borders and conforming quartered infill, the plinth base with stepped ogee top mouldings over conforming circular panel inlaid front flanked by canted angles, on ogee bracket feet.260cm (102.5ins) high excluding finials, 69cm (27ins) wide, 38cm (15ins) deep. Provenance: The Selwyn Demmy Collection. The case if the current lot is of particularly fine quality and essentially dates to around 1810. The overall attention to detail - in particular the precision of the inlay, crispness of the mouldings and superb column turnings indicates that the case was made by a leading workshop, hence would warrant a possible attribution to Gillows of Lancaster. The movement is also of fine quality but was made around 1900 and, in order to create room for the tubular bells/gongs, required the case to be increased in depth by around 2 inches. This work was executed extremely well with a great deal of effort taken to ensure perfect integration with the earlier elements. Indeed the sides of the trunk would have required r-veneering with the current arrangement of oval and circular panels no doubt being devised at that time to add decorative detail so to lessen the effect of the increased depth.

A RARE GEORGE III INLAID MAHOGANY MERCURY WHEEL BAROMETERBaptista Ronchetti, Manchester, circa 1790The 8.5 inch circular silvered register signed Bap'st Ronchetti, Fecit and with additional inscription H. Lomas, Adlington to the centre within scale calibrated in barometric inches incorporating an engraved motif of Masonic tools suspended from a ribbon and with the usual weather observations to outer track, set behind hinged circular glazed moulded wood bezel incorporating additional recording hand to the glass and with chevron line border decoration, the chevron-edged case with open triangular pediment above arch-glazed Fahrenheit scale spirit tube thermometer to the baluster shaped upright inlaid with fan quadrants to upper angles and three oval radial paterae to lower margin, the rounded base with further oval patera over conforming fan rosette.96cm (38.5ins) high excluding finial. Provenance: The Selwyn Demmy Collection. Baptista Ronchetti is recorded in Banfield, Edwin BAROMETER MAKERS & RETAILERS 1660-1900 as working from Spear Street Manchester from 1785 and then later at 15 High Street until around 1810. Ronchetti emigrated from Tavernerio, near Lake Como, Italy in 1785 later sending for his son, Charles Joshua, and his nephew Louis Casartelli who were both accompanied by Dominic Bolongaro. Initially all three worked in Ronchetti's workshop before branching-out and setting-up on their own. Baptista Ronchetti is a well-regarded maker known for his stick and angle barometers and was one of the first to produce wheel barometers of the type which subsequently became the predominant design produced throughout the 19th century. The current lot is notable in being a particularly early example of its type most likely being made in the 1790's. Early features include the hinged wooden bezel (which is secured by a lock with keyhole set in the side of the case) as well as the truncated design of the top of the case. The additional name engraved on the dial is for H. Lomas of Adlington who is recorded by Banfield as working circa 1800-20. The presence of Lomas's signature (executed in a different hand) would suggest that he probably re-sold the barometer perhaps 20 years or so after it was made.Condition Report: Tube is filled with no obvious airlocks, the float mechanism etc. is intact and operational however will require setting-up/calibration. The dial/register is in fine original condition albeit with some minor discolouration/tarnishing; the front glass is cracked and the bezel has had some minor historic repairs to the chevron line decoration as well as a small loss. The thermometer is in good condition although the tube is a replacement which may have required the aperture for the bulb in the plate to be enlarged slightly . The case is in good with limited to a few small losses/historic repairs to the chevron banding, some slight shrinkage cracking to the edge veneers and other minor bumps, scuffs and age related blemishes. Condition Report Disclaimer

They supplied the Admiralty, the War Office, the India Office and the Crown Agents for the Colonies and operated from several addresses in Glasgow and Edinburgh as well as from 14 Cross Street Hatton Garden from 1889. The business became a Limited Company in 1897 and continued to trade from the same London address until 1935. The current lot is made to the principles laid down by Nicholas Fortin (1750-1831) and incorporates a glazed cistern so that the level can be calibrated via the adjustment screw to the base against an inverted conical ivory cone in the cistern in order to obtain consistency in the readings. This particular type of barometer provides an accurate reading hence was generally adopted for laboratory use throughout the 19th and early 20th centuries.Condition Report: Instrument is filled with mercury and provides a good reading with no apparent airlocks.

A FINE GEORGE III MAHOGANY BAYONET-TUBE MERCURY STICK BAROMETER WITH LARGE SCALE THERMOMETERNairne and Blunt, London, circa 1780 The arched-top caddy moulded case inset with glazed hygrometer inscribed DAMP DRY and with beard setting square beneath over concave-topped silvered Vernier scale calibrated in barometric inches to the right hand margin opposing weather observations to the left, the upper margin signed Nairne and, Blunt, London and the lower edge decorated with an engraved leafy scroll flanked cavetto-shaped angles, the trunk applied with full-height silvered-scale mercury thermometer calibrated in Fahrenheit with scale divided in degrees annotated 0-120 opposing markers inscribed Freezing, Temperate, Sum'r Heat, Blood Heat and Fever Heat over spiral pierced brass bulb shield and circular base applied with half sphere cistern cover incorporating sleeved level adjustment screw to underside. 108cm (42.5ins) high. The collaboration between Edward Nairne and his former apprentice Thomas Blunt is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as established in 1774 and lasting until 1793. Edward Nairne was born in 1726 and apprenticed to the celebrated instrument maker, Matthew Loft, in 1741. Latterly he worked from 20 Cornhill and published numerous booklets on navigational, pneumatic and astronomical instruments. In 1776 Nairne devised a marine barometer with a restriction to the bore of the mercury tube which served to dampen the oscillation of the mercury, he was elected Fellow of the Royal Society in 1776 and died 1806. Thomas Blunt was apprenticed to Edward Nairne in 1760 with whom he formed a loose partnership in 1774, perhaps for mutual convenience as his premises were next door to Nairne's at 22 Cornhill. Blunt designed some of the components for the 'New Barometer' devised by the Portuguese Scientist J.H. Magellan for measuring altitude, and latterly became instrument maker to George III. In 1793 he took his son, also named Thomas, into partnership and subsequently relocated to 136 Minories in 1814, he died in 1822. A small group of bayonet-tube stick barometers incorporating a large scale thermometer by Nairne and Blunt are known. These include an example in The Whipple Museum, Cambridge (illustrated in Goodison, Nicholas English Barometers 1680-1860 on page 186, Plate 124); another previously in the collection of Edwin Banfield is illustrated in his publication BAROMETERS, Stick or Cistern tube on page 75 and a third was also sold in these rooms on 15th March 2018 (lot 38) for £3,200 hammer. These three differ from the current lot in that they do not have a hygrometer fitted however an example which also includes a hygrometer, hence is very closely comparable with the current lot, was sold at Lyon and Turnbull, Edinburgh, 19th May 2021 in their sale titled Five Centuries: Furniture, Paintings & Works of Art (lot 123) for £4,000.Condition Report: The tube is filled with mercury with no apparent airlocks. The register plates/scales have overall patchy discolouration and tarnishing to the silvering otherwise are in fine original condition with the delicate engraving showing very little wear suggesting that the plates have not been re-silvered many times in the past. The wheat beard to the hygrometer is currently detached otherwise is in good condition with the adjustment mechanism intact and working. The thermometer is in good condition; the brass fittings are however somewhat discoloured/tarnished. The case is in good original condition showing old but relatively flat surface with some wear mainly to the dome of the cistern cover. There is no key present to the hygrometer or level adjustment squares. Condition Report Disclaimer

Lot 189

AN IMPRESSIVE VICTORIAN MAHOGANY QUARTER-CHIMING LONGCASE REGULATORSmith and Sons, London, mid 19th centuryThe substantial four double-screwed columnar pillar triple train movement with plates measuring 9.75 by 10.25 inches and six-spoke wheel crossings throughout, the going train with Harrison's maintaining power and deadbeat escapement regulated by mercury jar compensated pendulum incorporating fine beat adjustment to crutch, the quarter train chiming on a graduated nest of eight bells and the hour sounding on a large coiled gong, the 12 inch circular single-sheet silvered brass Roman numeral dial with subsidiary seconds and STRIKE/SILENT, FULL CHIME/WESTMINSTER CHIME selection dials to the centre signed SMITH & SONS., ST. JOHN'S SQUARE., CLERKENWELL., with blued steel spade hands set within canted silvered bezel, the substantial case with ogee-capped concave-sided upstand, stylised twist baton carved cavetto cornice and repeating scroll decorated frieze over recessed quadrant panels around the dial aperture to hood door flanked by canted angles and with deep-set foliate scroll pierced arched sound frets to sides, the trunk with urn finials over complex top mouldings and repeating split baton frieze to throat above arch-glazed door enclosing silvered pendulum beat scale flanked by Egyptian style faceted three-quarter columns with stylised leafy caps and flared moulded bases, the plinth of inverted breakfronted form decorated with crisply moulded panels to front over tall skirt with complex upper mouldings.217cm (85.5ins) high, 66cm (26ins) wide, 34cm (13.5ins) deep.  The clockmaking business of John Smith and Sons of Clerkenwell can trace its roots back to 1780 however gained much greater significance when they became established in St. John's Square, at the former manufactory of Colonel Mangier, from 1844. The firm ran extensive workshops which incorporated a dedicated brass foundry, clock case workshop and assembly areas for the various types of clocks produced and was featured in the 20th September 1851 issue of the Illustrated London News in an article entitled Visit to a Clerkenwell Clock Factory. At the Great Exhibition held that year they exhibited a year going calendar clock and another chiming clock, chiming on 8 bells and striking on a gong. Ultimately John Smith and Sons perhaps became best known for their skeleton clocks, many of which illustrated in their 1865 catalogue including models based on Litchfield Cathedral and York Minster, however they also produced many fine chiming bracket clocks, longcase regulators, wall clocks and public clocks. The business continued to produce clocks until 1938 when, due to the decline in demand for mechanical timepieces, they diversified to become specialist material stockholders and still continue in this role today.It has been traditionally thought by vendor's family that the current lot was exhibited at the 1851 Great Exhibition. Although there is no evidence to support this, the movement and case are certainly of very fine quality hence would warrant this belief. Interestingly a quarter chiming longcase clock shown by Smith and Sons at the Paris 1900 Exhibition survives in the collection of The National Trust at Castle Drogo, Devon (object/902584). This clock also has a three train four pillar movement with Harrison's maintaining power, mercury jar pendulum and chimes the quarters on eight bells or four gongs, and is housed in an elaborate Chippendale style gilt brass mounted mahogany case.Condition Report: Lot 135The movement is in fine clean fully working condition having being relatively recently serviced (prior to the former owner's death). The level of mercury in the pendulum needs topping-up (is low) and there is staining to the interior of the glass jar. The dial generally is in fine clean condition but does have a couple of light spots of tarnishing.The case is in fine condition with faults limited to the small section of angled cornice moulding to the front right hand side being detached (just need gluing back on!); one small section (approx 1 inch) of the unusual repeating block decoration to the trunk door missing; a small loss to the front left hand corner top moulding of the base and a small loss to the left hand side fret. Otherwise faults are very much limited to minor bumps, scuffs, slight shrinkage and wear (most notably to the skirt) commensurate with age and use.Clock is complete with pendulum, three weights, case key and winder.Maximum dimensions at base - width 67cm (26.5ins), depth 35cm (13.75ins). Condition Report Disclaimer

He worked for several barometer makers before setting up alone and subsequently traded from several addresses in King Street and Duke Street, Liverpool and died in 1860.Condition Report: Tube is filled with no obvious airlocks, the float mechanism etc. is intact and operational however will require setting-up/calibration. The dial/register is in fine original condition albeit with some minor discolouration/tarnishing; both setting hand mechanisms are operational. The thermometer is in good original condition. The case is in fine fine condition with faults limited to the carved crest having the tip of a leaf missing from the apex. Otherwise faults are very much limited to a few very minor bumps, scuffs and other age related blemishes. Condition Report Disclaimer

AINSLEY, MAKER AND ADJUSTER OF, Iron Ships' and Steamers' Compasses, 86 BUTE STREET, CARDIFF... to the inside of the lid; together with a 1.5 inch two-draw refracting telescope, circa 1875, signed R. & J. Beck, 31 Cornhill, London to final draw, with shuttered eyepiece, sliding brass sun shade, end cap and leather grip, complete with cylindrical leather protective case, (2).The sextant box 32.5cm (12.5ins) high, 29cm (11.5ins) wide, the telescope case 27cm (10.5ins) long. The name W.B. Moralee of North Shields appears not to be recorded as a maker of instruments hence could well be that of the first owner of the octant in the current lot. At some point the instrument was with Thomas Liddell Ainsley of Cardiff and South Shields (whose trade label is pasted to the inside of the lid) who was a maker of precision instruments active between 1858-1886. Ainsley also published numerous works on marine navigation and related subjects with his best known work being A guide book to local marine board navigation. The Ordinary Examination first printed in 1859 with no less than 45 subsequent reprints up to 2018. The telescope I the current lot is by Richard and Joseph Beck who is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as first working from 31 Cornhill 1867-80 and then 68 Cornhill from 1868. They were best known for supplying microscopes and other optical instruments which were presumably constructed in their factory at Lister Works, Kentish Town, Holloway, East London. Banfield further notes that they often signed their instruments 'R & J Beck Ltd' from 1894.Condition Report: The octant is in complete original condition with all fittings present. The mirror has some degradation to the silvering mainly towards the margins and one of the filters has some slight edge chipping where it is fitted into its mount. Both the Vernier in the arm and the main scale each have a single crack bot no losses. Otherwise instrument is a little dirty/neglected but in good order. The box has corner chips to the top and base panels as well as overall age related wear and shrinkage otherwise is in sound original condition.The telescope has some slight discolouration to the margins of one of the internal lenses otherwise optics appear to be in good original condition and the instrument will focus. The draws appear to be free form noticeable dents or cracks as does the sun shade but there is some noticeable discolouration/tarnishing to the brass. The leather grip is in fine condition, the shutter to the eyepiece and the end cap are also in good condition. The leather outer case is also in good original condition although the carrying strap is no longer present. Condition Report Disclaimer

A FINE PATINATED AND GILT BRONZE TABLE REGULATOR WITH SIX-LEGGED GRAVITY ESCAPEMENTSinclair Harding, Cheltenham, circa 1985-90The circular gilt four double-screwed columnar pillar single chain fusee movement with Harrison's maintaining power, external six-legged gravity escapement incorporating jewelled pallets pivoted beneath sub frame mounted on the backplate, and regulated by half-seconds pendulum with wire rod and large diameter heavy gilt brass cylindrical bob, the 6 inch circular silvered dial with eccentric Roman numeral chapter ring interrupted by slender subsidiary seconds ring at six o'clock and with separate outer minute track, applied onto the frosted silvered ground over two curved plates signed SINCLAIR, HARDING to lower margin, with blued steel spade hands within canted gilt circular surround, the case with fluted urn finial to the gilt line bordered stepped cavetto moulded panel upstand over keystone latch for the full-height bevelled front glass and rectangular section patinated bronze corner uprights incorporating horizontal gilt line details at the base of the arch, the sides with curved glasses following the profile of the arch over gilt rail and further rectangular windows, the rear matching the front, the interior with gilt floor applied with silvered pendulum beat scale calibrated 5-0-5 and engraved with serial number 869, on stepped black marble plinth base with chamfered edges and canted angles over brass ball feet.56cm (2ins) high, 26cm (10.25ins) wide, 23cm (9ins) deep. The Cheltenham based clockmaking firm Sinclair Harding was established by Bill Sinclair and Mike Harding in 1967. Between 1971 and around 1995 the business evolved from being initially focussed on restoration and repair to designing and building their own clocks including chiming longcase and table clocks, their design of 'sea clock', giant and perpetual calendar carriage clocks. In 1995 Mike Harding retired leaving the firm in the hands of Robert Bray; the following year Sinclair Harding were commissioned to make the clock for the Oval cricket ground and the business was relocated to North Yorkshire. In 1999 their first scale version of John Harrison's sea clock was produced adding to their ever increasing catalogue of complex timepieces, and 2010 saw Robert Bray awarded the Barrett Silver Medal by the British Horological Institute as well as being appointed Vice President. The firm have always been regular attendees at Baselworld and in 2017 exhibited their Harrison H1 timepiece at Salon QP. The Gravity escapement in the current lot has its roots in the exploratory designs of some of the leading late 18th and early 19th century makers such as Berthoud, Mudge, Cumming and Hardy. Bloxam had come close to perfecting the design in 1853 however was still plagued by the fault encountered by earlier attempts in that the pallets tended to bounce off the escapement locking surface; known as 'tripping'. Edward Denison (later Lord Grimthorp) perfected the gravity escapement in 1860 by eliminating the tripping problem. He did this through the connection of a fly (air brake), directly to the escape arbor via a friction clutch. It allows the fan to advance slightly after the escapement engages the pallet. The inertia provided by the weight of the fly keeps the escapement seated against the pallet during locking; in essence acting as an 'energy sink'. This escapement provides a nearly detached pendulum from the rest of the clockwork and, as there is no sliding friction, there is no need to oil the escapement. These features made the escapement perfect for use in turret clocks where a high degree of accuracy can be maintained with minimal maintenance. There are two principal designs of gravity escapement the first is the double three-legged type the second in the four legged design. The former uses two pairs of three legs for the pallets and three impulse pins at the centre whilst the second has four legs and four pins. The disadvantage of the both of these designs is that the escape arbor revolves either 1/6 (double three legged) or 1/4 (four legged) for each beat of the pendulum hence the train of the timepiece needs suitable long gearing to maintain a reasonably long duration. The current movement is unusual in that it utilizes a six legged arrangement which has no doubt been employed to facilitate running with a half-seconds pendulum.Condition Report: Movement is in very fine original condition retaining the original gilding and bluing to the screws etc. blemish free. The mechanism is in working condition however has not been run in a while hence the action of the escapement is prone to slowing-up a little due to the lubrication of the pivots having dried out. With this in mind the mechanism would benefit from a gentle/light service before putting into service. The dial has a very slight scratch to the chapter ring between the VII and VIII numerals otherwise is blemish free.The case is in fine condition with faults limited to slight wear and a small corner chip to the lift-out rear glass panel (which cannot be seen when the panel is in place). Timepiece is complete with a crank winding key. Condition Report Disclaimer

A RARE PORTRAIT OR MEDALLION REDUCTION LATHEUnsigned, mid 19th centuryThe substantial triangular bed applied with two sliding perpendicular faceplate assembles, one larger than the other and with worm gear drive to rear sharing the same long horizontal driving screw terminating with stepped wooden pulleys to right hand side, the front applied with complex pin-pivot assemblies for the mounting and operation of the tracing and cutting bar with the right hand also automatically adjusted in the vertical plane by an arrangement of worm gears connected to the that driving the faceplates, the whole raised on open rectangular end uprights with out-swept hipped feet onto a rectangular platform base cut with slots for bench mounting, (incomplete). 72cm (28.5ins) wide, 28cm (11ins) deep, 36cm (14.25ins) high. The current lot is designed to create a smaller copy of a relief decorated medallion using a system of fine gearing, pivots, detents and a beam to geometrically project a tracing of the pattern mounted on the larger faceplate plate onto the smaller secondary plate at a smaller scale. This form of lathe, which uses principles similar to that of a pantograph, were developed in France during the late 18th century. The current lot however appears to be an English model very much in the style of Henry Maudslay (1771-1831), a British engineer who developed a series of finely engineered lathes for screw-cutting and other purposes during the late 18th and early 19th centuries.Condition Report: The lathe is incomplete as there is a block to the centre of the beam which has vacant pivot holes as well a yoke also with vacant pivot holes to unattached end. The smaller wheel appears to be a replacement. At the large wheel end is a vertical slide controlled by a fine screw fitted with a pivoted double-yoke assembly which also has vacant pivot holes to the second yoke again indicating that an additional part of the mechanism would be attached at this point.

The firm became one of the most prolific makers of scientific instruments and continued trading well into the 20th century.The current lot is an example of a Fishery or Sea Coast storm barometer devised by Admiral Robert Fitzroy in the 1860`s to aid mariners in the forecasting of storms. Interestingly the scale only incorporates one Vernier scale (rather than usual the double scale) hence recording daily change in barometric pressure would have had to be done by taking notes rather than using the second scale. Fitzroy lobbied the Board of Trade resulting in this type of barometer being supplied (at public expense) to many coastal communities for display in a prominent public space. In addition to this The Royal Lifeboat Institution installed these barometers into each of its stations and the Duke of Northumberland (in association with the British Meteorological Society) erected several on the coast of Northumberland. By 1864 over 80 barometers had been installed by the Board of Trade and a further 14 by the Duke of Northumberland with their usefulness fully appreciated in Fitzroy's Meteorological Office Report published that year.Condition Report: The tube is filled with no apparent airlocks and both Vernier slide is fully operational. The scales have some slight overall crazing and the left panel of the scale has a small hairline crack across the top right hand corner. The thermometer is in good working condition however the scale has overall stained crazing. The case is in good original condition with only minor bumps, scuffs and other age related blemishes. Condition Report Disclaimer

Over the next decade he travelled back and forth between England and Bombay however in 1879 his wife Mary sadly died in Kensington which led to a period of special compassionate leave. In November 1884 Keith Jopp was furloughed again but was back in Bombay in December the following year having been promoted the Lieutenant Colonel, Royal Engineers. He was by this time Deputy Consulting Engineer, 1st Grade in the Public Works Department at Madras and by time of his retirement in 1891 he had been further promoted to rank of Colonel. In the 1901 census Keith Jopp was recorded as a retired Colonel residing at 69 Eaton Rose, Ealing; by 1911 he had moved to Atheldane, Westgate-on-Sea, Kent and his death was recorded at Thanet in spring 1920. Condition Report: Instrument appears complete and is in working condition albeit with some noticeable wear and light bumps, scuffs etc. The mirror has some noticeable degradation of the silvering to the margins, the Vernier scale has only light rubbing/wear but is still legible when viewed through the magnification lens.

Simmons at 7 St. Ann's Square Manchester in 1871 where they remained until 1905. In July 1872 they installed a shop regulator with a galvinometer connected to Greenwich at their premises (designed by Edward Salomons architect) incorporating an exterior clock dial with a Greenwich style falling ball dropping at 1pm daily. This was reported in the Manchester Guardian, and no doubt provided endless publicity for the new proprietors. The current lot would appear to be that very regulator as it is fitted with a galvanometer which would be receive an electrical impulse from Greenwich every hour causing the needle to 'flick' exactly on the hour. As the 'shop regulator' the present timepiece would have served to set and check the time of watches in the showroom as well provide accurate 'Greenwich Mean Time' to the public.

Watchmakers & Clockmakers of the World as working circa 1720-80 and in around 1795 respectively. Joshua Drabble appears to have been an accomplished maker with a regulator by him being one of the first items donated to the Royal Astronomical Society. This timepiece was formerly the property of Colonel Mark Beaufoy, one of the first members of the Royal Astronomical Society, and was presented upon his death by his son, George in 1827. This regulator was often loaned out to fellows and actively used in scientific experiments in the years after it came to the Society, before returning to Burlington House where it remains central to the Society's historical legacy. Condition Report: Movement is in clean working condition and is free from any visible alteration or significant replacements. The main enamel dial disc has feint hairline star cracking to centre as well as another between the VII and VIII numerals; the surface also has overall very light flecking to the fired surface which appears to be from manufacture which is best described has having the appearance of light paint overspray.

The case is in fine original condition with noticeable faults limited to some shrinkage cracking to the arch of the top. Faults are otherwise very much limited to minor age related bumps and blemishes. The veneers of the case have fine colour/patination.Clock is complete with pendulum, winder and two case keys.Please ask the department for additional images Condition Report Disclaimer

Watchmakers & Clockmakers of the World as working from Drury Lane, London before 1772 and was a freeman of the Clockmakers Company 1781-94.Condition Report: Movement is in clean working condition; the escapement has been converted from verge to anchor albeit with minimal intervention to the plates (ie. has only a very small slot cut to the centre of the top plate to allow for the pallet arbor). The rise/fall regulation beam has been retained the backcock however appears to be a replacement. The base of the case has been cut with a slot to allow for the current longer pendulum and a thin panel applied to the underside to close the hole. The backplate has an unused treaded hole and adjacent steady-pin hole for a pendulum hold fast which is no longer present. Movement otherwise is in good original condition with no other obvious alterations or significant replacements.The dial is in sound original condition with nice detailing such as the engraved infill around the subsidiaries in the arch. The hands appear original, the matted surfaces appear a little dull on colour compared with the rest of the plate and the silvering has some patchy tarnishing to the finish, the false bob pendulum has been retained despite the conversion of the escapement from verge to anchor.The case is in generally good original condition. The top exhibits some very slight shrinkage cracking and movement but this is minimal; the left hand pad has small but noticeable scuff/bruise to the centre of the panel. The mask around the dial (behind the front door) has had a small section of veneer re-attached at the base of the arch to the left otherwise is in fine condition. The door retains its lock and hinges and the raised mouldings around the glazed aperture appear complete with no obvious replacements although some shrinkage cracking is evident; the key hole has a small adjacent veneer chip to a historic veneer patch repair evident due to an area of darker colouring. Both sides have very slight chips to the veneer ovelaps bordering the brass sound frets otherwise are in good condition. The rear door has a 2 inch section of moulding to the arch replaced (not the best quality repair) otherwise is in good original condition retaining lock and hinges. The case has old French polish and wax finish which has mellowed and there are minor historic bumps, scuffs and other minor blemishes commensurate with age.Clock has a pendulum and winder but no case key. Condition Report Disclaimer

A JAPANNED AND LACQUERED BRASS FORTIN-TYPE MERCURY STICK 'MOUNTAIN' BAROMETER Pasterelli and Rapkin, London, early 20th centuryThe instrument with slender cylindrical case pierced with a vertical slot to reveal the tube incorporating sliding Vernier collar reading against a scale calibrated in barometric inches ranging from 20 up to 32.5 inches to the right hand margin opposing millibar scale to the left, the shaft with Vernier adjustment disc to right and engraved signature PASTORELLI & RAPKIN, 46 HATTON GARDEN, LONDON to centre over applied mercury tube Fahrenheit and Centigrade scale thermometer with canted scale and enclosed bulb to front, the base with cylindrical glass chamber enclosing mercury and incorporating inverted ivory level pointer to interior clamped between horizontal plates over cylindrical cistern and adjustment screw to base, mounted via a brass ring to top and base collar-bracket with triple securing screws onto a rectangular moulded mahogany panel with curved top and base.The instrument 102cm (40ins) high; the wall panel 105cm (45.5ins) high, 9cm (3.5ins) wide. Provenance: The Selwyn Demmy Collection. The firm of Pastorelli and Rapkin are recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as being established in 1872 as a prolific maker of barometers of all types of barometers who worked from 61 Hatton Garden and 7 Great Warner Street, London in 1872 and then 46 Hatton Garden from 1873. The firm was incorporated as a Limited Company in 1901 and was still trading (in various guises) until 1988.The current lot is made to the principles laid down by Nicholas Fortin (1750-1831) and incorporates a glazed cistern so that the level can be calibrated via the adjustment screw to the base against an inverted conical ivory cone in the cistern in order to obtain consistency in the readings. This particular type of barometer provides an accurate reading hence was generally adopted for laboratory use throughout the 19th and early 20th centuries. The scale of the present lot is unusual in that it ranges from 20 up to 32.5 inches rather than the usual circa 26.5 to 32 inches. The facility of being able to read particularly low pressures is indicative of an instrument intended for use at high altitudes hence instruments that incorporate this feature are sometimes referred to as 'mountain barometers'.Condition Report: Instrument is filled with mercury and provides a good reading with no apparent airlocks and the Vernier slide is operational. The brass case is in sound condition but has patchy strong discolouration and wear to the original lacquered finishes. The back panel is in good condition. Condition Report Disclaimer

He was apprenticed to Reid and Auld of Edinburgh and was admitted to the Clockmaker's Company as a Free Brother in 1822. Around this time McCabe entered into short lived partnership with Strahan (probably Charles who gained his freedom of the Clockmaker's Company in 1815). From 1826 James McCabe managed the business alone from 97 Cornhill until 1838 when he was forced to temporarily relocate to 32 Cornhill due to a major fire at the Royal Exchange. Condition Report: The movement is in relatively clean working condition and appears all-original with no visible evidence of alteration or significant replacements. The dial has been restored to a reasonably high standard. The movement and dial are original to the case and the case is in fine condition with faults very much limited to very minor historic bumps and scuffs. The baseboard of the case has a hole in the centre suggesting that at one time the case was probably fixed to a wall bracket at some time in the past.Clock is complete with its original pendulum, case key and a winder. Condition Report Disclaimer
