Click here to subscribeA Miller Dunn 'Divinhood' Navy Standard (style two) shallow water diving helmet by Miller Dunn, Miami:, brass handle to top, with circular comms connection cap and safety chain, side air intake, squared and angled front windows with double bar guards, stamped 'B12' to the window surround, copper weight mounts to front and back, 61cm high. see page 3, vol 1, 'Diving Helmets and Equipment Through The Ages'.
A brass reproduction in the style of Siebe's Open Dress Helmet of 1829:, the non-opening front and side windows of equal size with guards, rear air intake and exhaust pipes, the smaller air inlet to the front is sealed during conversion from a smoke helmet to a diving helmet, 50 cm high. *Anthony Pardoe notes - In the Siebe Gorman Book 'Deep Diving & Submarine Operations' it is claimed that the original of this helmet was made in 1819. This is disputable, as the first open helmet was invented in 1823/24 by the Deane Brothers; and the Siebe helmet was a later development of this, and became known as the Open Dress. Although the one shown is not an exact copy, it is very similar to Siebe's first helmet. * see page 23, vol 1, 'Diving Helmets and Equipment Through The Ages'.
A 1907 Siebe & Gorman 'Pattern 200' Diving, Smoke, and Submarine Escape Helmet:, the copper helmet with single round hinged window and guard covered with a canvas waist length suit fitted with an adjustable jock strap,77cm long. *Notes- In 1907 Sir Robert H.Davis, managing director of Siebe Gorman & Company, in conjunction with two naval officers Admiral Hall C.B.E. and Fleet Surgeon O.Rees, designed the above apparatus using the chemical "Oxylithe". This is a special preparation of sodium peroxide which when breathed on gives off oxygen, and at the same time absorbs carbon dioxide from the expired air. The Oxylithe was placed in a metal container in a front pocket inside the suit top of the 'Open Dress'. It had a mouthpiece and tube leading to the canister and an open end tube from the canister to the top of the helmet. This helmet had a triple purpose, for although designed as a submarine escape apparatus it was also used as a shallow water diving helmet, but could also serve as a smoke helmet without the necessity of an air supply. It was stated that on one charge of 'Oxylithe', working in smoke or diving at shallow depth, the apparatus could be used for 45 minutes. However with further research it was found to have another use. An adaptation of this apparatus was also sold for use when capping oil wells, with the jacket having long rubber gloves glued to the sleeves, and air supplied by hose and bellows into a connection in the top of the helmet. The pocket holding the canister of "Oxylithe" is inside the suit and also has a strap to hold it in place. If it was used for diving in cold waters, a wading dress was worn under the suit with normal lead boots and a weight belt of 65 lbs. Chest weights could not be used as they would obstruct the breathing lines. It was essential that the diver maintained an upright posture to prevent the water getting near his mouth, as breathing had to be done through the mouth in order for the system to operate correctly. If he needed to pick anything up he would kneel or go down on his haunches, but not bend down. This helmet was purchased from an old gentleman in Bristol. He told us that he was a cabin boy on a large sailing vessel, and that it was used as the diving helmet on the ship. He took the helmet and had held on to it for over 60 years, being too afraid to sell it. The suit was rather smelly when purchased and still retains some of the 'aroma'. see page 24-25, vol 1, 'Diving Helmets and Equipment Through The Ages'.
A shallow water diving helmet for the Ford Motor Company possibly by Charles Person:, the four observation windows with guards, stamped to crown with Ford logo and 'Agencia P. Grossa', the bonnet attached by a series of eight nuts and bolts, rear air inlet, the plain corselet with front and rear weight hangers, 42cm high. * Notes- Similarities in style and construction to the helmets of Charles Person may indicate that this helmet was made by him for the Ford Motor Companies Brazilian factories. Ford had their own helmets for divers to keep the water inlets and outlets clear of obstruction at their various plants. * see pages 26-27, vol 1, 'Diving Helmets and Equipment Through The Ages'.
An open suit diving helmet by Person, Sao Paulo, Brazil:, the four observation windows with guards, the front window with additional bar for removing the faceplate, rear inlet and side adjustable outlet valve, the bonnet attached to the corselet by 12 bolts, maker's plate to breastplate as per title, front and rear weight hangers, attached to a red leather half length diving dress, height of helmet 42cm. * see page 28, vol 1, 'Diving Helmets and Equipment Through The Ages'.
A copper and brass one -piece mine recovery diving helmet:, number '0367', circular top window with guard, drop down oval front window, rear inlet and outlet, comms and side automatic control valve, the shaped corselet with post weight hangers to the shoulders, 41cm high. * Anthony Pardoe's details on the helmet are thus -'This non-magnetic helmet had a two piece suit. The neck of the suit top was attached with glue to the underside of the corselet; and the trousers had boots attached. Both the top and trousers had a long rubber 'skirt' extension at the waist which were carefully rolled together to form a watertight seal; over this a rubber cummerbund was stretched to prevent the seal from unrolling or leaking. A self contained pack of inverted aluminium alloy cylinders, worn on the back, fed oxygen into one of the openings on the back of the helmet. This was connected inside to a convolute tube with a mouthpiece, from which the diver - wearing a nose clip - breathed. The front window hinges down to allow the diver to communicate or breathe fresh air when on the surface. Air was exhausted through the second outlet to the 'scrubber' in the self contained unit which removed the CO2. It was topped up with more oxygen to be fed back through an automatic control valve, which could be overruled by the diver to obtain more oxygen. The outlet valve has a large rubber diaphragm and exhausts air much quicker than the normal valve if necessary, though it still has the spindle and wheel adjustments. The comms connection gave communication with the surface if required; otherwise the set was self contained. All the equipment worn had to be non-magnetic.' * see page 31, vol 1, 'Diving Helmets and Equipment Through The Ages'.

The owner / instructor thought that with so much use it needed extra protection - hence the fibreglass. * see pages 40 -41, vol 1, 'Diving Helmets and Equipment Through The Ages'.
An early 6-bolt self -contained re-breather diving helmet by Siebe Gorman & Co ,London:, number '10711' (matching), circular front and oval side windows with guards, spitcock, rear inlet and outlets, angled telephone port, side outlet with cog, the corselet with hanging posts and reserve valve, rounded 12-bolt brails converted to six bolt, 46cm high. * Anthony Pardoe notes- 'Though it has never had a badge this is a Siebe Gorman 6 bolt Re-breather Helmet. It is shown in Deep Diving and Submarine Operations, Fourth Edition page 153. It could be used to depths of 150ft for up to 1 ½ hours. Being an early model it does not have the larger head, as it is not a conventional Deep Diving Helmet. It was one of the first helmets used as a self contained re-breather, and could have been used experimentally as a Deep Diving Model. * see pages 42-43, vol 1, 'Diving Helmets and Equipment Through The Ages'.
A 6-bolt Admiralty pattern diving helmet by Siebe Gorman & Co,London:, oval side windows with guards, circular front window, spitcock, side outlet , rear inlet and telephone, the corselet with maker's plate as per title, 46cm high. * Notes-This is an example of a helmet that was scrapped by the Admiralty. A pick axe was put through the top and other parts damaged or destroyed before discarding. It has been rebuilt - but not very well. Though the front view appears normal, closer inspection shows the copper of the corselet is almost separated from the brass surround. The outlet valve is untidy and the hole alongside would have had a lanyard hook attached. However the holes in the top and the inside air vents have been well repaired. The Admiralty markings AP 7985, with their emblem the broad arrow and AB are stamped above the front window. The side window surrounds are also stamped 378 & 916 but have been replaced with odd nuts and bolts which can be seen. The comms inside have been poorly replaced. * see page 44-45, vol 1, 'Diving Helmets and Equipment Through The Ages'.

It is the only helmet I have ever found with a brass top'. * see pages 50-51, vol 1, 'Diving Helmets and Equipment Through The Ages'.
A full size carved wooden replica of a 12-bolt diving helmet after Siebe Gorman & Co by Seahorse Enterprises:,number '005' oval side windows with guards, circular front window, spitcock, side hooks rear air intake and outlet valve, the corselet inscribed as per title, with weight posts and brails, 51cm high. * see page 52, vol 1, 'Diving Helmets and Equipment Through The Ages'.

A 12-bolt Mk V diving helmet by Siebe Gorman & Co, London:, number '19422', (matching) the oval side windows and guards rotated 90 degrees to accommodate the Morse 'banana' exhaust valve, circular top and front windows, the former with guard, front spring loaded safety catch, rear air inlet and comms, telephone cap to the upper right, the corselet with maker's plate as per title, weight hangers and counter struck brails, 52cm high. * Notes- This helmet was designed by an English North Sea Diver called Ron McKenzie, together with an American Diver, both in conjunction with Siebe Gorman. The divers were working with a Davis Submersible Decompression Chamber in the North Sea. They wanted a helmet which the diver could remove by himself if necessary when he climbed into the chamber after deep diving. The safety catch was put close to the front window so that it was easily located, enabling the diver to remove the helmet in order to decompress using oxygen. Not many were made, because just as it had been designed, standard diving was coming to an end in the North Sea due to the depth at which they had to work. Modern helmets took over as they were more suitable for mid water and deep diving. * see pages 54-55, vol 1, 'Diving Helmets and Equipment Through The Ages'.
A 12-bolt diving helmet with patent speaking apparatus by Siebe Gorman & Co, London; numbered '6322':, oval side windows with guards, circular face plate, lashing eyes and tear drop spitcock, rear air intake and side air outlet, fitted speaking tube to right of faceplate with blanking plug stamped ' Gorman patent London', and internal diaphragm, also fitted internal air ducts, the corselet with weight hangers and raised text manufacturer's plaque, wing nut to brasses, the brails stamped as per title, 46cm high. *Anthony Pardoe notes - The most intricate work would have been the speaking tube and fitting it to the helmet. Siebe helmets with speaking tubes are difficult to find as very few were made. The telephone communication system was introduced within a short time and was safer and clearer, therefore speaking tubes became obsolete and most helmets were returned to the factory for conversion to telephone. The small canvas bag covering the air inlet was probably put on by the last diver and is a good indication of how well they looked after their equipment. It was not only their livelihood, but also their safety that they treasure' * see pages 56 & 57, vol 1, 'Diving Helmets and Equipment Through The Ages'.

However E.J.Willis Co. of New York, who specialised in Marine Equipment, put out a catalogue in 1937 in which they showed a picture of a helmet exactly like the Snead, but they called it the Willis Diving Helmet. This pattern was most probably prior 1935' see page 6, vol 1, 'Diving Helmets and Equipment Through The Ages'.
