Diving Equipment & Supply Co 4 Light Heavyweight Commercial
This diving helmet is an excellent representation of a commercial diving helmet that help build the USA directly after World War 2. The helmet was made by the Diving Equipment and Supply Company (DESCO) in Milwaukee, WI on February 20th, 1946. It is a model 29134, aka the Heavyweight 4 Light Commercial Helmet.
As the name implies, this helmet was designed for the most rugged underwater work. It does utilize many features found on the famed US Navy Mark V helmet. The basic differences of this helmet from the Mark V is the breastplate style, larger threaded faceplate, and three oval lights (windows).
It is notable that this helmet was ordered only months after World War 2 ended. While the military had thousands of Mark V helmets in inventory, the commercial diver market was likely starved for new equipment. Also surprising is the condition of this helmet. Somehow the helmet has remained in an incredible original state! The original thinning on the copper body is almost 100% intact. All of the fittings, air vents, glass, guards, brails, wing nuts, brail shims, springloaded safety bolt and latch, communications wire, neck ring gasket, Schrader non-return valve, communications elbow cap, etc. are still present. The serial number on the ID and both inside neck rings are matching as well.
As with any helmet that was used, there are a few very minor working dents on the top of the bonnet. An authentic patina has formed on the helmet, giving it the unmistakable original untouched look prized by many collectors. This model is still be produced by the good folks at DESCO today, a testament to its rugged design and excellent quality. Don't pass up an opportunity to own one of the very first 4 Light Heavyweight Commercial diving helmets ever made!
