A lovely example of a scarce helmet by famed makers Heinke. Designed for work in shallow water in places like docks and harbours, on jobs like inspecting and or repairing vessels, buoys, jetty’s etc.

This one is in great condition, the previous owner used to dive it commercially. Remnants of its original tinning. A point of interest for this variety of hat is the hinged front window and the two types of exhaust valve, the star wheel for normal use and the one with the ring attached is a dump valve for quick release of air in an emergency.
