I recently picked up a 4X Kollmorgen Bear Cub Scope with a post reticule to put on my '03-A3 sporter. It is in excellent condition for a scopes made in the '50's, and very clear. The only drawback is it has a 26mm diameter body, so I will have to modify rings to fit. I understand that Kollmorgen sold it's scope line to Redfield in 1959, and the scope has some collector value. Does anyone have any other information?
