Gunner is right P Kohler produced scopes that were used by SS Police/Heer police during WW11. The scopes used, the alloy ocular bells seem be marked P. Kohler Berlin 4x and P. Kohler Berlin Pecar 4x. It may be that the 4x only marked scopes were purchased direct for military and the Pecar 4x marked commercial ones procured by other means or confiscated. The scopes during WW11 have distinct range dial markings and some have rifle serial numbers engraved on tube, others not. I am collating further information on these scopes if anyone has one used during WW11 and is willing to pass on details/pictures.

The tube size of scope is 27 mm and a friend of mine has just removed a set of Redfield rings from an original military scope if shooterjim is interested.

Any serial number on your 6 x 59 scope shooterjim?
