This is the famed and highly coveted United States Navy Mark V diving helmet. This helmet was made by Diving Equipment & Salvage Company on June 6th, 1944 – also known as D-Day. It is unnecessary to go into the significance of that day in this description, however, having an authentic piece of US Navy equipment made on that day is very special and unique.

As shown in the photos, this Mark V helmet is just about as clean and nice as can be found, not even considering his historical importance. All the old gray tinning has been worn or polished off many years ago. The result is a warm consistent patina to the copper body and brass hardware components.

Vitally important to Mark V helmets is the serial numbers, especially one made in D-Day. This DESCO is indeed serial numbers matching on both inside neck rings and the brass ID plate. DESCO would place the numbers on the inside as opposed to Morse and Schrader examples. An additional VERY important detail, a US Navy inspection stamp is present on the neck ring. This stamp is proof the helmet was inspected and accepted into US Navy inventory on that historic day!

The helmet does have all four brails, 12 wing nuts, window guards, glass with original red lead sealant, air and communications fittings, DESCO stamped non-return valve with cap, communications fitting cap, spitcock, and exhaust valve, dumbbell safety latch with original chain (one end loose) and cotter pin. Inside the bonnet, the internal air vents are all present as well as the exhaust valve chin button. The original neck ring gasket is present. If any flaw can be pointed out, then a few very minor working dents on the bonnet are present. These tiny dents are simply reminders that this helmet actually did see use many decades ago. Overall, the helmet is an incredibly desirable example in amazing condition made on one of the most important days in US history!
