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 in diving. Their helmets would be used by the Royal Navy and her many colonies throughout the 19th and 20th Centuries. The Admiralty Pattern was the Royal Navies primary deepwater 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 inside neck ring of the bonnet & breastplate. They would also place a number on the front window frame as well. The breastplate has #10072, the bonnet #12161 and window frame #10168. It has been our experience that more often than not the #’s are not matching on helmets like this model.

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 2 brails rather than the four found on 12 bolt helmets. The back of the bonnet features the original air & 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 condition and perfect for display in the home or office. The copper body and brass hardware exhibit a wonderful patina. The helmet is complete with all its glass, 6 wing nuts, 2 brails, exhaust valve, air fitting, communications fitting, spitcock valve, dumbbell safety latch, window guards, neck ring gasket, original reproducer (speaker) and internal air vents.

This helmet exhibits a classic English look and beauty. Hints of light use are evident in the copper bonnet. Such a classic design and model do not turn up often, especially in the American market. This helmet makes for an excellent example to sit next to a US Navy Mark V to show the peak of copper/brass helmet design by both nations militaries.

All helmets sold & auctioned by Nation’s Attic Inc. will come with a certificate of authenticity (COA). This COA will have a serial # on it that will match the # on a tamperproof holographic decal placed on the inside of the helmet. This level of security and long term assurance of the helmets authenticity is un-matched in the industry and very important to us.

The display stand shown in the photos is not included. The option to purchase one after the auction will be provided. All helmets will be shipped in two double boxed boxes via FedEx. Worldwide shipping available. A shipping quote prior to the auction can be provided by emailing your postal code.
