Zeiss 'blc' 7x50 UDF U-boat deck binoculars

A very nice pair of the highly sought-after Carl Zeiss 'blc' coded 7x50 UDF U-boat deck-mounted binoculars!
 
Each U-boat would have carried two of these binoculars (one as a spare), with this particular optic being mounted at the front of the U-boat conning tower. They were a key part of the U.Z.O. (Uberwasser Ziel Optik or U-boat aiming optics) that was used to launch torpedo attacks on vessels whilst surfaced.
 
They are produced with a solid bronze body to ensure they were pressure resistant down to ~300m depth and, as such, could be safely left attached to the exterior of the U-boat in the event of performing an emergency dive manoeuvre. 
 
This particular example remains in very good original condition. Whilst there are clear signs of use and wear, as you would expect and indeed probably wish to see from such a piece, the vast majority of the wartime applied paint layers remain intact througout. 
 
The optics still produce a usable image, with the vertical aiming line reticule still present and perfectly visible inside. They also still retain the ocular width adjustment bridge on the underside, which remains perfectly functional. 
 
Arguably the most iconic of all U-boat related binocular optics, and one which would make for a remarkable display piece within any collection!
