Historic Deep-Sea Diving Suit - Classic Copper Helmet Gear #3062283 (License: Personal Use)

This black-and-white line drawing depicts a traditional surface-supplied deep-sea diver wearing a heavy-duty canvas suit, brass-copper helmet with viewing ports, and lead-soled boots. The diver holds an air hose and lifeline, illustrating the critical life-support and communication systems used before modern scuba. Such suits enabled salvage, construction, and inspection work at depths unreachable by free-diving methods.
