I recently added a 1961 vintage near new comdition Husqvarna rifle to my collection and it came with a Byshnell Banner 4X-12X x40 variable scope in Weaver Tip-Off mounts. The front ring on the scope is movable and has range graduations on it. I was wondering roughly what vintage the scope is and what the use of the graduations are for.
The scope seems to be in near mint conditiob and is probably pretty old but I'm guessing not as old as the rifle.
Any info offered will be greatly appreciated.
