WW2 German Kriegsmarine Officers Binoculars Leitz 7x50 These are Naval Officer binoculars with rubber eye covers, primarily used on U-Boats, though not exclusively. Manufactured by Leitz they are the Porro II variation. Marked 'BEH 453492' under the rubber cover on the left optic. Both rubber covers are missing their lids, otherwise rubber cover in fair condition. Right optic has very small damage on bottom right when looking through however, majority of lens is in great condition with no clouding whatsoever. Bag with binoculars is not original. However, leather strap attached is original. Range and optic change is found underneath both rubber covers, therefore each optic can be changed individually.
