Zeiss 7x50 Kriegsmarine Küstenartillerie binoculars 'Artl.' + case

A scarce pair of early-war Kriegsmarine binoculars which were specifically issued to Küstenartillerie (Coastal Artillery) personnel, but could also be found in use aboard seafaring vessels and U-boats etc. 
 
They are a pair which, despite clear signs of use, remain nicely inscribed with the Carl Zeiss Jena maker's logo - as well as having the early style of KM Reichsadler eagle property marking. 
 
The optics still remain in usable condition as they are, but could also still benefit from an internal cleaning if desired. They still retain the correct KM crosshair rangefinding reticule inside! 
 
A totally 'as found' set from here in the UK which comes complete with the correct original Kriegsmarine Zeiss weatherproof case - even still intact with the shoulder strap!
