SMGP-2371 Kriegsmarine Binoculars d.f. 7×50 by Carl Zeiss W/sun guards

A nice set what shows wear and is missing the leather strap on the case. The optics eye cover strap is town and tied in a simple knot. The optics are usable and relatively clear, but a full breakdown and service would clean them up a bit more. Included is a full set of sun guards to make viewing in daylight easier i presume. Not sure what the actual term for these guards is. The binoculars are stamped with the Navy Eagle and M.  The case is unmarked and in good used condition. The spring catch is functional, and the springs have been permanently twisted. I assume with was to add tension to the worn out springs.
