1922 ARROL-JOHNSTON 15.9HP `THE ONE DOOR` TOURERRegistration Number: DL 2560Chassis Number: 3701Arrol-Johnston, one of Scotland`s early motor manufacturers, often produced unconventional models. The first came in the successful form of the Model 10 Dogcart in 1898, which was equipped with an opposed-piston, flat-twin 10 horse power engine. Several models then followed, with four cylinder and 23 horse power, six cylinder engines.This rare `One Door` Tourer was based at Penman Engineering, Coachbuilders of Dumfries, who restored DL 2560 for the Dumfries Octo-centenary celebrations in 1986; the Penman Works were in fact just half a mile away from the original Arrol-Johnston factory at Heathhall. The motor car has also been part of the Sword Collection and in the early Nineties, it was purchased by a Mr Bob Dixon. We understand that while in the care of the Penman`s, the Arrol-Johnston was used and rallied by the works supervisor, Mr Ian Gray, who estimated the top speed of about 38mph from the 2613cc engine. This important Scottish vintage motor is supplied with the V5C registration certificate and publications with references to the car. Careful recommissioning may be appropriate following museum storage. See illustration (FP and detail of interior)

A rare exhibition scale model of a side lever paddle engine of the `Wilberforce’, built by Mr A Young of Tyne and Wear over a period of four years from his own research and drawings taken from `The Steam Engine’ by Tredgold published in 1838. The Wilberforce was a packet built in 1836/37 by Curling & Young - Blackwell for the Humber Union Steam Company which ran between the ports of London and Hull. This model is built to a 1/2 inch to 1 foot scale, the original engine being 285 horse power with 60 inch diameter cylinders with 72 inch stroke to a design by Francis Humphreys and built by John Hall, being the first marine engine with condensers. The piston valves were also unique catching the interest of Brunel during his initial engine enquires for the `Great Britain’. This historical model has architectural columns and archway supporting a twin open crank with split bearings and decorative cast metal linkage beams. The cylinders being 2 1/2 inch bore by 3 inch stoke with inside mounted piston valves and partly lagged in planked mahogany with brass bands. It has central positioned condensers with air and sea water pumps linked to the under beams. Due to the scale of the model some items such as oilers and other small parts are finished for appearance only. The model is finished in light grey paintwork with polished brightwork and is supported on a section of wooden ship’s hull. Some photographic build evidence and plans come with the model. Transportation case. The model 25cm high, 26cm wide, 35cm long.
