What stories could this helmet tell after more than a century?
We are pleased to offer this remarkable A. Schrader’s Son diving helmet, a fascinating survivor that appears to represent two distinct eras of American diving history.
Originally manufactured as a five-bolt helmet consistent with the U.S. Navy Mark II, it likely dates to the early 20th century. After the Navy adopted the Mark V in 1916, older helmets like this were too valuable to simply discard. During the Great Depression, this helmet was likely returned to Schrader and modernized with an interrupted-thread neck assembly for continued use.
Even more interesting, Schrader purposely omitted modern communications fittings during the conversion—possibly at the request of a commercial diver or company that preferred traditional “old school” rope-pull communication.
And then there is the patina! Close to a century—or potentially more—has given the copper body an incredible deep chocolate-brown surface, beautifully complemented by naturally aged brass hardware. This is a likely survivor of both U.S. Navy and American commercial diving history, and the helmet still carries physical clues to its earlier life.
Offered at $6,999 delivered within the contiguous U.S. when paid by check, money order, or bank wire.
