Just put some money down on a Model 10-5 snubby today. The 10-5 was made from the early 60s through the 70s, if I recall. If the serial number begins with "C" it's 1967 or earlier.
Ninety-eight percent blue, original grips, tighter than ... well ... a drum. I probably paid too much, but I don't see many forty-year-old revolvers in such good shape.
