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.

This is an early 1930s style Chang Jin Diving Equipment Manufacturing Company diving helmet from Korea (South).

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.

The Chang Jin Diving Equipment Manufacturing Company is one of the oldest manufacturer's of diving equipment in Korea and they were still trading in old and new helmets in 2007.

During and after the WWII period a Chinese diving equipment company by the name of 'Bo On' retailed Korean diving helmets adding their 'Bo On' name tags to the Korean helmets they sold on. 'Bo On' is no longer in business.
