Rare WW2 US Navy Submarine Target Binoculars

Rare WW2 US Navy Submarine Target Binoculars.

Super rare, super cool set of great optics, WW2 U.S. Navy Ships Mark 91 6×50 Submarine Torpedo Targeting Binoculars, made by Bausch & Lomb Optical Co.

These would have been mounted on the Submarine conning tower and remained on the bridge when the submarine dived hence the spectacular engineering and unusual stainless steel composition, which although a very scarce and expensive commodity in WW2, was used to combat the effects of sea water and the enormous pressures.
