These old-fashioned copper "hard-hat" diving helmets were originally constructed for Russian Navy Special Forces, who required protection from the extraordinary pressure (up to 7 atmospheres) incurred on extreme-depth dives of 200'. We rescued a few from a Navy surplus warehouse in St. Petersburg. Most are in perfect/unissued condition and arrived coated in the original cosmoline grease, which protects the metal from tarnishing. We have hand-polished them and, in time, they'll develop a beautiful patina. Front and dual side windows with rubber gaskets and brass frames. Approximately 19" high and 44" in circumference. Weighs a massive 32 lbs. Three 1" diameter bolts connect the helmet to the 58" circumference neck/shoulder mounting platform. Quantities extremely limited.
