Scarfed up a vintage Weaver K2,5 post reticle scope, plus vintage rings, bases, for my 1949 Winchester Model 70.
I know the scope is from about 1949-1950 because of the bubble type adjustment covers, the black dials and the external screws on the saddle. See here, on a Savage 99:
K2.5 Ad from 1949 The rings are the Weaver single piece type, and I needed to take off the ocular and the lock ring to mount the rear scope ring.
