Siebe Gorman Diver’s 4 Pronged Light
Presented is a British Siebe Gorman chromed brass
deep sea diver’s flashlight. All types of torches are made from high-quality brass (probably Admiralty or Naval qualities) and most were electroplated(mainly chrome plated) for added protection against corrosion. This working light is an example of one of the fine pieces.
In 1975, Siebe Gorman moved from their ‘Neptune Works’ at Chessington in Surrey, to a new location at Cwmbran in Wales.
By this time, the manufacture of diving equipment had declined, and the new factory concentrated on firefighting apparatus.
However, ‘switchless’ diving torches were still made with the Cwmbran address stamped on the casings.
The rugged, simple construction of the different types of Siebe Gorman torches enables them to operate within the depth parameters of most
normal diving. All torches are powered by three ‘D-size’, 1.5-volt dry cell batteries. It was suggested in the Davis Manual that torches should not be switched on until underwater, to prevent cracking of the glass lens by the cold water. Torch models with a glass ‘bullseye’ lens give relatively good illumination for close work (good in poor underwater visibility) but the beam is short on distance.
Dimensions: Lgth; 11 1/4″ Dia. of head: 3 1/4″ Wt: 2 lbs. 13 oz.
The last 4-prong torches produced by Siebe Gorman at their Welsh factory (post 1975) have a full casing stamped address and
N-S number which reads: SIEBE GORMAN & Co Ltd AVONDALE WAY CWMBRAN, GWENT. REF.No. 6230-99-942-7885 (fig.14).good illumination for close work (good in poor underwater visibility) but the beam is short on distance.
