This is an original pair of WWII German dienstglas 6x30 binoculars. They were manufactured by Carl Zeiss in Jena, Germany. The lack of a factory code, serial number of 980922, and brass construction all indicate early-war production. The H/6400 marking denotes the presence of a range-finding recticle in the user's right-hand lens. These show wear and significant use, but are still in good, displayable condition.
