RARE consecutive production Zeiss 7x50 KM binoculars 'blc'

Now here is a real rarity and remarkable stroke of fate - 2x pairs of mid-war Zeiss Kriegsmarine 'smooth ocular' binoculars, as often issued to and seen in use with U-boat crews etc, that are as close as can be to being consecutive production numbers...
 
They are both clearly marked with the Carl Zeiss Jena maker code 'blc', as well as the serial numbers '37502' & '37504', respectively. 
 
The example serial numbered '37502' is still fitted with the original Bakelite 'Benutzer' ocular cover - and this is even inscribed with the name of the owner 'Lohr' ! 
 
As to be expected with quality Zeiss binoculars such as these, the coated lens optics on BOTH pairs still produce a very clear and usable image. 
 
All in all, a truly unique one-off opportunity to obtain a set of 2x binoculars which were produced directly alongside each other, and which are now both reunited together again some 80+ years later!
