Early Zeiss Kriegsmarine 7x50 binocular case + filters

A scarce early variant of storage case for the Kriegsmarine 7x50 binoculars produced by 'Carl Zeiss Jena'. 
 
This particular model is made from the typical black rubberised ersatz material, and remains exactly as it was found. 
 
The case is nicely maker marked, alongside the Kriegsmarine eagle 'M IV/1' proof marking -  the latter of which is still intact and has not been erased like seen on many examples today. 

Indeed even the leather shoulder strap - also matching KM proof marked! - still remains present and attached! 
 
Internally, all 4 lens filters are intact and this case comes with 2x original lenses. 
 
All in all, a very nice and scarcely seen accessory which would make a great addition to a pair of Kriegsmarine issued Carl Zeiss 7x50 binoculars!
