Around 10 years ago, if I recall correctly, S&W did a run of what it called the Model 22 / Model of 1950. This was a square-butt fixed-sight N-frame with 4 inch lightweight barrel and a shrouded ejector rod in 45 ACP, using moon clips for ejection. It came with pre-World War II style small wooden grips. (The Model 21 / Model of 1950 was the same gun in 44 Special, without the moon clips, of course.)
I thought it was one of the handsomest revolvers I had ever seen, and finally managed to buy a used one for about $900 several years ago. I have no idea if that was a good price or not. The single-action trigger pull on mine is excellent, as light and crisp as a target gun. I don't think the previous owner had it tuned. The double action pull is good too.
I was fortunate in that it shot to point of aim for me, and despite the fact that I dislike heavy recoiling guns (32 Long is more my speed), I found it to be an excellent shooter.
The main problem with it was grips. The little factory grips were very handsome but too small for good control. I guess S&W does not make square-butt N-frames regularly anymore, so the selection of grips was more limited than for a round-butt gun. I finally settled on some old Pachmayrs, but there is room for improvement there.
As shooters, the Model 625s have all the advantages - stainless steel, adjustable sights, a heavier barrel, and a much wider selection of grips. But I simply found that the Model of 1950 re-issue appealed to me more, and it turned out to be a first-rate shooter too.
Before that, I had a Colt 1917. It had been refinished, so although it looked nice, it had no collector value. The SA trigger on it was also excellent, and I think it was definitely tuned. The DA pull was long and heavy. It shot very well, but ONLY with 230 gr FMJ - the bore was a bit rough. I finally sold it because the sights become too small to see with my aging eyes.
PS - this shows what the S&W Model 22 looks like:
