As stated in the previous chapter: the danish 2 bolt divers helmet was invented by Peter Hansen Hessing. As a diver working for the danish salvage company ‘Svitzer’ he had learned to dive with the antique ‘Sadler’ diving equipment. The Sadler was in fact an open helmet with a jacket attached to it, based on the very first design of diving equipment. Peter Hansen Hessing used the Sadler helmet as the base for his own helmet and improved the design by giving it a breastplate which could be built to a ‘one piece’ suit with the use of a neck ring and 2 bolts. He patented his helmet in 1907, it is believed that he never built any helmets himself but designed them and had them built by local craftsmen. In early 3013 a Sadler helmet was found which had been converted to a 2 bolt helmet, it is not impossible that this helmet is in fact the very first 2 bolt helmet ever built(!) Would there ever be found any evidence for that then this will of course be published in this website ...
