CG/45 REGULATOR - The CG / 45 regulator from La Spirotechnique began to be marketed in 1946 and its first version, very rare, is immediately distinguished by two striking differences. The first one concerns the absence of the plate bearing the name of the manufacturer and the address: in its place there is only the serial number engraved directly on the back of the body, nearby the yoke. The second difference is in the mouthpiece assembly, here consisting of a simple smooth curved metal tube on which the actual mouthpiece is applied. Only in the 1947 the model will come out with the plate and the linear mouthpiece assembly with the ring nuts for tightening the hoses

DRY SUITS - Next month we will inaugurate a new section dedicated to historical dry suits. Looking at the many models produced in rubber foil up to the mid-1960s, a question arises: why in the first 25 years were they produced without valves, ie without the possibility of compensating them, with the considerable inconveniences that came from? Why nobody thought about that in the 1950s when the emergency Bcd was already here, (with a bottle of compressed air) ? There was only a few wetsuit with a small tube on the chest used to release the air trapped inside before the dive; in some cases it was certainly also used to introduce air into it with the mouth. Was it possible that the first to apply the fill and drain valves was Poseidon with its neoprene Unisuit in 1968? Does anyone have different information about it? Please share with us your knowledge
