WW2 German Carl Zeiss S.F.14z Periscope Binoculars

An excellent original condition with good clear optics and range festivals still intact. This is a very early made set by Carl Zeiss who made very few SF14 compared to the other main manufacturers. This set I believe made in the late 1930's and then sent back to the factory during the war to be re-greased as indicated by the blue circle
