6x30 Dienstglas 'Carl Zeiss Jena' binoculars
A good, used example of early-war 6x30 Dienstglas field binoculars produced by Carl Zeiss Jena.
This example retains much of the original factory-applied black paint finish and black leatherette covering to both barrels.
The optics would require an internal service to return them to a fully usable state if desired.
Overall, however, still a nice pair of 6x30 by a desirable maker!
