Just got back from a "Mom & Pop" sale- older hunting clothes, ammo, fishing tackle, magazines- besides some NIB .35 Whelan (Remmie) and almost a full of the first series Win AA 28 gauge skeet loads (No 9 shot)- I bought a NRA VG plus Winchester Model 75 (a keeper) and a older Weaver steel 1" scope- no serial number, marked WEAVER KV and inside a stamped border 60-- EL PASO, TEX. USA. PAT'D and inside a circle A-- elevation knob on top, windage on the right side ( 3'o'clock position from TDC) and a third knob, smaller with cap, set for 5X with arrow pointed clockwise, and 3X with the arrow pointed counterclockwise- may hang it on one of the 8 .22LR's I own with Weaver or similar 1" scope rings- the windage and elevation knobs move freely, as does the rear threaded ring- clear as a bell, std fine crosshairs- Have to think it is pre-1964 as there is NO Zip Code for El Paso, TX on it- no serial number, unlike my favorites, the Leupold scopes-- any ideas, lads??
