Rare black and tan Pressstoff case for the Bakelite 6×30 binoculars

Stunning and extremely rare carrying case for the 6×30 bakelite binoculars executed in black and tan(!) Pressstoff. The case is marked CXN 4 indicating production by Emil Busch. The case was sent home at the end of the war by a US soldier who noted his details to the top. This is the pinnacle of collecting Ersatz and surely one of the most sought after pieces in equipment!
