Arguably the most desirable and collected diving helmet in the world, the United States Navy Mark V. This example was made in June of 1942 by the A. Schraders Son Company, Division Of Scovill Mfg. Co. Schrader was one of the original two companies to manufacture the Mark V for the US Navy starting in 1916. Schrader would land numerous contracts during World War 2 to produce the Mark V. This example is an early WWII Mark V considering production had not increased dramatically until 1943 and 1944.

All USN Mark V diving helmets made for the US Government had the copper body coated in a tinning. This tinning helped prevent saltwater corrosion to the copper. From use, age and polishing this time wears off in many cases. This example had the copper body painted black long ago. The black paint does give the helmet a distinctive appearance. If so desired, luckily the paint could be removed relatively easily.

Vitally crucial to Mark V helmets is the serial numbers. During 1942 Schrader would place the serial number on the ID plate and on the bottom side of all four brails. This helmet features the number 244A on the ID plate and all four brails!

This helmet does feature a US Navy inspection stamp. The inspector at the Schrader factory would place the symbol on the top edge of the communication cup. This helmet features the stamp in that spot and is proof the helmet was inspected and accepted into US Navy inventory!

The helmet has all four brails, 7 of 12 wing nuts, all wing nuts are flanged style, modified window guards, glass, air & communications fittings, communications fitting cap, spitcock, BTE exhaust valve, and dumbbell safety latch and chain. Inside the bonnet, the internal air vents are all present, as well as the exhaust button. Neck ring gasket is not present. A seldom seen telephone is still inside with wire running to the communication fitting.

It’s very likely the Mark V was purchased as surplus after World War 2 and used by a commercial diver. The diver likely modified the the window guards, applied the paint and installed the unique telephone system inside. Replacement window guards and wing nuts can be acquired from both DESCO and Schrader if so desired. This helmets uniqueness, early WWII date and matching serial number status make it a great example for any collection.
