Rare Kriegsmarine issue 7×50 Dienstglas marked bmk

Rare Kriegsmarine matching 7×50 power binoculars with the top and rain cover maker marked bmk 1943 indicating production by Srb & Stys Fabrik Praziser Messinstrumente, Prague. The binoculars are clear and well collimated. The oculars are the rare flip up type for Kriegsmarine troops. The right ocular has no Strichplatte in place.  A very nice pair of binoculars that would be impossible to upgrade!
