The Mark V diving helmet was manufactured for the US Navy from 1916 until the mid-1980s. During that time there were only four manufacturers of this model. The first two companies to make the Mark V were A. Schrader's Son and the A.J. Morse & Son Company. Initially, there was a strong demand during and after World War 1 for the helmets by the military and commercial divers.


When World War 2 started, another huge wave of demand was created for the Mark V. Not able to meet the full demands of the US Government, 2 more helmet manufactures made the Mark V. Miller Dunn in Miami, FL and Diving Equipment & Salvage Company in Milwaukee, WI joined Morse Diving Equipment Company and Schrader who was then a division of Scovill. During WWII literally, tens of thousands of Mark V's were produced! After the war, the Mark V was a favorite of commercial divers and would continue to be used by the US Navy. Today the Mark V is still being made by DESCO & Morse. While not used as commonly for diving work, the Mark V is a favorite of ours and many of our customers as a piece of diving history. If you have a Mark V helmet please let us know, you might  be surprised just how much we can pay!
