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.

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.

These Chinese helmets were designed for the average sized Asian person, making the helmet (bonnet and corselet) smaller and lighter than the average American or European helmet. China still produces dive helmets similar to this one today.
