Lot 124:
Description
When conjuring the image of what a classic English diving helmet looks like, the 6 bolt Admiralty Pattern helmet made by Siebe Gorman comes to mind. Siebe Gorman started making the first diving helmets in the 1830s in London, England. The company would continue to invent innovative new designs and technology for diving. Their helmets would be used by the Royal Navy and its many colonies throughout the 19th and 20th Centuries. The Admiralty Pattern was the Royal Navy’s primary deep water helmet in the 20th Century.
This fantastic helmet is a style primarily used by the Royal Navy before, during, and after World War 2. The helmet features the original Siebe Gorman brass ID plate. Siebe Gorman would stamp serial numbers into the inside neck ring of the bonnet & breastplate. They would also place a number on the front window frame and the bottom side of the two brails or straps. The serial #13064 is stamped on all five locations, a full number matching example from the 1938!
Of important note, the the frame of the faceplate also features a broad arrow stamp. This proves the helmet was in the Royal Navy inventory and no doubt part of the war effort!
The standard configuration for this model utilized oval windows on the side and a round threaded window on the front. The 6-bolt pattern only requires two brails rather than the four found on 12 bolt helmets. The back of the bonnet features the original air and communications fittings. When looking at vintage photos of English military hardhat divers, there is an excellent chance this very model is what you will find being utilized.
The helmet is in excellent original unrestored condition, perfect for display in the home or office. The copper body and brass hardware exhibit a wonderful, consistent patina. Surprisingly, a large majority of the factory-applied tinning remains on the copper body. The helmet is complete with all its glass, 6 wing nuts, 2 brails, exhaust valve, air fitting, spitcock valve, dumbbell safety latch, window guards, and internal air vents. The top of the bonnet is free of any notable dents as well!
This helmet exhibits a classic English look and beauty. Such a nice example with a broad arrow stamp rarely turn up often, especially in the American market. One that served during WW2 is even more special.
The display stand shown in the photos is not included. The option to purchase one after the auction will be provided.
