History and use
This helmet is in the Siebe Gorman standard dress style (Admiralty Pattern). The centre front light (window) does not have a grill cover. There are two (2) side lights (windows) with grill covers. This helmet has four (4) weight lugs, two (2) each on the front and back of the corselet.

Although stylistically similar, this helmet was built for the harsh Korean marine fisheries and is without features such as spitcock or telecommunications. The bonnet is typically soldered at the crown with two seams front and back, this is a cheaper method of construction, melding parts together rather than hand beating a sheet of copper over a mold. This particular helmet shows signs of repair on the crown and has been fitted with a rope lanyard.

Siebe Gorman designed the first successful diving helmet (used in the excavation of the ship 'Royal George' off Portsmouth, England) in c.1840. The Siebe helmet and fittings design proved to be so reliable that Siebe’s ‘standard diving dress’ became the British Admiralty’s benchmark for all diving equipment.

During and after the WWII period this model sometimes bears the 'Bo On' label; the Chinese company Bo On only sold diving equipment, they did not produce it. They put their name tags on Korean helmets that they sold on.
