i have what i have been told is a sight from a german ww2 tank that my grandfather brought home from the ETO, but he passed before i was born, so i know nothing about it but what ive have been told.
is what i have been told correct?
it has the german word "Klar" on it, which means clear, as well as "Filter" which is obvious.

The knob cycles two filters in the scope, one that filters a small amount of light, and the other fliters quite a bit more.
The eye piece also revolves left and right (up and down like its threaded) to control what i assume is the focus of the lense.
