History and Use Before WWII

The Italians had used the English Siebe Gorman diving equipment but this supply was soon cut upon their alliance with Germany at the commencement of WWII. The Italians began their production, the most famous being the Galeazzi company. Founded in 1938 by Roberto Galeazzi, the company became especially famous for the production of all kinds of hyperbaric diving equipment, atmospheric diving suits, observation chambers and oceanographic research systems. Besides this, they produced diving helmets in three (3) styles: Marina (Italian Navy Standard), Grand Luz (Large Faceplate) and Titano (Lock Device Neck Ring).
