Zeiss 7x50 Kriegsmarine gas mask binoculars 'blc'

An excellent condition example of the mid to late-war Kriegsmarine issue Zeiss 7x50 'gas ocular' binoculars, as issued to coastal troops, those stationed aboard surface vessels and U-Boats! 
 
This untouched pair set comes complete with it's original factory-fitted Bakelite 'Benutzer' ocular guard, as well as the leather neck strap and button tab exactly as they were found. 
 
The original rubber eyepieces, designed to be used in conjunction with a gas mask if needed, remain in very good shape and are still fully extendable. The Carl Zeiss Jena 'blc' maker code and serial number are marked to the right-hand prism plate. 
 
As to be expected with top quality Zeiss binoculars such as these, the optics remain excellent (crystal clear) and focus superbly well. All lenses are coated. 
 
These binoculars are now getting quite hard to find in this condition, especially complete with accessories such as the original Benutzer rain cover. They would make the perfect addition to any Kriegsmarine or optic collection, as well as being an item that is still very much suitable for use today!
