The Zeiss 6 x 30 and 8x30 were the first commercial binoculars produced by the West German Zeiss firm after the second world war. These binoculars were delivered with a partial rubber armor. Few still have it.
This Zeiss Dienstglas has got a characteristic short body, with spaced objectives and a 6-lens ocular design. It was apparently in service with the German Border Control until recent years.
