Zeiss 7x50 Kriegsmarine binoculars 'Flak Küste'

A scarce pair of early-war Kriegsmarine binoculars that were issued to the coastal anti-aircraft Flak troops. 
 
They are nicely inscribed with the Carl Zeiss Jena maker's logo, as well as retaining completely intact original KM property markings to both prism plates. 
 
Interestingly, this particular pair have been retrofitted with the fixed Bakelite eyecups as are quite commonly seen on wartime factory-reworked Zeiss binoculars (instead of the more fragile rubber gas mask variants).
 
They also come fitted with the correct original leather Benutzer ocular cover. 
 
The optics still remain in useable and functional order to this day, but would also benefit from an internal clean if desired for usage purposes. Notably, the correct Flak crosshair rangefinding reticule is retained inside also!
