SIEBE GORMAN ROYAL NAVY DIVE HELMET
Shallow Water & Deep Water Rig Included
Stand Not Included!
Presented is an authentic 6 bolt, 3 light Siebe.Gorman Royal Navy
pattern helmet from the mid 1930's era . It was previously owned by a professor of microbiology who used
it off the coast of California for deep water under water research, and in the Gulf of Mexico where it was used with special
weights as a shallow water rig. It has been handed down in the same family for the past 50 years and this is
the first time it is being offered for sale. The original brails have gone missing and recent replacements have
Note missing spitcock handle
CONDITION and MARKINGS:
The helmet originally was tinned, but over the years had become oxidized, and had mostly worn off. This distracted
from the overall appearance of the bonnet and breast plate. It was recently polished.
The worn tag reads Siebe Gorman
& Co. Ltd., Submarine Engineers, London, Patent. The breast plate has number 9534 stamped on the inside
back neck ring. The bonnet number, 9529, appears on the back inside of its neck ring. These numbers are 300 lower
than the "Boots" Serveno helmet we sold last year which was owned by that family for 46 years. The air passages inside
are intact, the relief valve works, and the front door opens. The spit cock was mounted upside down by the factory and
its handle is broken off. There is a telephone elbow on the back with a large size hex cap marked "telephone",
but the inside speaker is missing. All the port lights are in excellent original condition. There are numerous small
dents on this helmet which attest to the service it performed over a career of underwater research. The brails are
recent replacemets and are marked "Front".
DIMENSIONS OF HELMET: 19" H x 14 1/2" W
WEIGHT 48 lbs
BRIEF HISTORY: Augustus Siebe the German-born founder
of the firm which bears his name (1788-1872) is considered "the father of diving". Siebe's 'closed' diving
helmet, first produced in 1840, allowed divers to dive safely to greater depths than ever before. Attached to a rubber suit,
it became the 'Standard Dress' that revolutionized diving and made the underwater worker an essential part of both salvage
operations and civil engineering. Many of the great building projects of the Victorian era - bridges, tunnels and lighthouses
still in use today - could not have been built without divers.
Siebe's design was so successful that it remained in use, essentially unchanged,
until 1975. However, the Royal Navy required one of their own design, and the British Admiralty requested a helmet
made to their specifications which used heavier materials in 1938. This was the Royal Navy six bolt helmet, as seen
in this offering. The rest of the "Jake" was standard commercial equipment, except for the front weight which had a light
fitted to it, to aid the diver. The chest weights weigh about 40lbs. each and are tied down to stop the helmet rising from
the diver’s shoulders. The weights are hung from weight hangers on the front of the breast plate.
The Royal Navy set out to extend
the limits of deep diving and established a world depth record, in 1948, of 540-feet wearing a Seibe Gorman helmet
of this design, but incorporating a Davis Injector system, flexible dress, and used the fast dwindling
supplies of American Lend-Lease helium. Petty-Officer Bollard set the depth record that was to last eight years.
Not until 1956 would the baton pass to another.
In October of that year, Senior Commissioned Boatswain George
Wookey, descended to a depth of 600-feet, setting record for a helmeted diver wearing flexible dress that still stands.
