A terrific example of a more challenging to find Soviet diving helmet called the 3 bolt 12 bolt pattern! This helmet was made at Factory 21, located in Leningrad, in 1983, as indicated by the brass ID plate.

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 copper body is in excellent condition with no notable major dents or damage. The bonnet and breastplate fit together with ease. The large rubber neck ring gasket is present. The ID plate features a date of 1983.

The 3 bolt 12 bolt style helmet allowed for the use of two different diving dresses. The traditional Russian 3 bolt dive dress could be used, or a dress used more commonly in the West, the 12 bolt pattern. Regardless, this helmet provided options and was undoubtedly more expensive to produce, hence why they are not found as often today. This helmet is a wonderful example of Soviet-era diving technology nearly impossible to acquire during the Cold War!
