Standard diving equipment was (and still is) used all over the world for all kinds of work. Companies like Siebe Gorman and Heinke even adjusted their helmets for different kinds of diving specialties. For sponge and pearl diving purposes for instance, front and side windows had no guards and were larger, the breastplate was square shaped because divers had to bend over much. TOA, the famous Japanese company, even designed a helmet especially for FEMALE divers. In salvage work, divers operated in and under ships, the chance of breaking a glass was much higher in this kind of work so their helmets had metal guards over the windows.
