Historical Deep-Sea Diving Communication System - Early Underwater Operations #62870 (License: Personal Use)

This black-and-white technical illustration depicts a standard early deep-sea diving setup: a diver wearing a weighted, sealed diving suit with a copper helmet connected by a lifeline and voice tube to a surface operator. The operator, dressed in a formal coat and cap, uses a headset labeled “R” (likely for receiver) while monitoring equipment housed in a box with dials and gauges, possibly tracking air supply or depth. Coiled hoses and electrical cables lie between them, indicating a hybrid pneumatic-electrical support system typical of late 19th- to mid-20th-century commercial diving.
