My Mom bought a used semi-auto .22 circa 1970 and remembers paying 179 or so dollars for it. Short on cash a few years later she sold it even though she loved the piece. I'd love to find the model, maybe even buy it if only for nostalgia. I gathered some clues from her as to features since she can't remember the model or brand - it's been 35 years. She remembers it being thin, very well balanced, and ejecting cases out the bottom of the gun. She also remembers buying a silencer with it, but not using that much. My thought was it may have been a modified Browning semi-auto .22 Grade 1 (bottom ejection), but she also remembers the gun being fed by a removable magazine. I'm having a hard time imagining an action that bottom-ejects and feeds from a removable magazine, but that's what she remembers. In summary, memory lists these features: .22 rifle roughly 179 dollars used in 1970 light, thin, and well balanced bottom-ejection removable magazine-fed (?not sure on the feasibility of this?) could attach a silencer (aftermarket/custom barrel?) My best guess is still some sort of Browning semi-auto, but was wondering what your thoughts all were?
