WW2 German Carl Zeiss 7x50 U-Boat Binoculars

A good set of WW2 U-Boat 7x50 rubber armoured blc maer coded (Carl Zeiss). Optically perfect with crystal clear view although one of the prisms has a slight crack in one of the corners (hence price) but this does not detract from functionality whatsoever and can only be observed when looking through them in reverse/backwards. Detached repro benutzer eye piece cover also included that just needs a new rubber cord/string.
