A fantastic example of a classic Soviet diving helmet in seldom encountered 12 bolt 3 light pattern! This helmet was made at Factory 21 in 1972, as indicated by the brass ID plate. Loosely translated, the plate says Russian Soviet Federative Socialistic Republic; 21st Expedition Party / Group Of Underwater Works; Leningrad.

As shown in the photos, the helmet has a wonderful patina to the copper body and brass hardware. All the correct hardware is present, including the window frames, brails and wing nuts, exhaust, air, and communications fitting. The old neck ring gasket is no longer intact. Also featured is an original Russian underwater light secured to the top of the helmet. Undoubtedly this helmet was used considering the air and communications lines coming out of the back of the bonnet.

The copper body is in excellent condition with only moderate small working dents on the peak of the bonnet. The bonnet and breastplate thread together with ease. The single safety thumb bolt on the back of the neck ring is present and working. The air vent along with communications hardware is present inside the bonnet. The ID plate features a date of 1972, which appears to be over stamped the date 1963.

Factory 21 twelve bolt helmets are relatively difficult to find, especially ones that have been lightly used and feature a light on top. The helmets patina also give it an appearance of a helmet that been part of underwater adventures, making it a stunning display piece!
