Arguably the most desirable and collected diving helmet in the world, the United States Navy Mark V. This example was made during September 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.

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 still retains a noticeable percentage of the original tinning. The toning and patina this helmet exhibits provides no doubt it was used.

At some point in this helmets history the ID plate was replaced. While close to the original, the current one appears to be a re-cast. It is possible the original ID plate had been removed and a replacement was better than having nothing in its place. With the serial number located on the communications cup, we are extremely confident this helmet was indeed made during September of 1942. Schrader would also place the helmets serial number on the bottom side of the brails. This helmet had recently been removed from a WWII era dive dress. During removal it was discovered that the brails were severely stuck to the old dress rubber collar. With great effort the brails were removed without damaging them. The result however is the bottom side of the brails being covered in very hard old rubber, obscuring the serial number. With patience this hard rubber can be removed, reveling the numbers.

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, 11 of 12 wing nuts, window guards, glass, air & communications fittings, Schrader non-return valve, air hose fitting with barbed end, communications fitting cap, spitcock, BTE exhaust valve, and dumbbell safety latch and chain but missing outer latch. Inside the bonnet, the internal air vents are all present, as well as the exhaust button.

The top of the bonnet does have a few working dents, but none are severe. Old flecks of white paint are evident in spots as well. This helmet has a great looking authentic patina from World War II. With a minimal amount of cleaning and care this Mark V could be even better!
