A beautiful example of early Zeiss craftsmanship and optical excellence. Mechanics and optics excellent. This was used on a military binocular or spotter for the German army of WWI.
I will include a 16mm Belgian helical focusing eyepiece that my be used when adapted to fit 1.25" adapters. Erfle wide-angle design and fully multi-coated. Very sharp!
