After looking at 19 pages of Smith and Wesson 22's, I somehow feel like I'm dipping into the wrong end of pool with my one example, but it is the only one I have now.
It's a 1951 22 Masterpiece. Nothing really fancy or unique about it I suppose. Not even a good picture. Just a good shooting 22. No box or papers, but the numbers all do match. I need to shoot it more.
The one I really hate that I let get away was a 4", Colt Official Police in 22 LR. The only one I've ever seen.
