World War II German binoculars were marked 'Dienstglas' meaning service glass. Pre-war glasses used by the German military had the maker's name. Often it was Zeiss.

From 1939/1940 onwards they used a code to identify the maker. The code usually appeared on the back of one of the prisms.

There were a huge number of manufacturers that made glasses for the German military. Some were in occupied countries. Look down the list to see Paris and Warsaw-based businesses.

There were also well known German manufaturers, Zeiss and Leitz, which had several different factories.

Hi Geoff, There is something about black cats here - It looks like they were a branch of the Indian Army. The binoculars were made by Hensoldt Werk fur Optic u. Michanik, Herborn KF is a cold weather marking. Indicating that they were made cold climates. Possibly for the Russian front. I hope this helps
