I can't find a model designation on this 38 special revolver. Serial number is 6 digits and starts with 961xxx. It is in really nice shape, a guy at work needed some money, hopefully I didn't over spend but it is in real nice shape
S&W did not designate their handguns by "model numbers" until the mid-1950s and it was a few years after that, 1958 I think, when they started stamping the model numbers on the frame where the cylinder crane meets with it when the cylinder is closed.
I've seen and fired 1940s era K- frame Smiths that did not have any model number stamped on them. But the same basic gun with a few minor tweaks would later be designated the model 10.
PSrumors, your revolver seems to be wearing the post-1968 style of Smith & Wesson K frame square butt stocks. They do not have a diamond around the screw hole. Older guns made before about 1968 would have the older style stocks with a diamond oriented vertically as shown in Adam5's gun pic.
But, it's not unusual for people to change out well-worn or cracked old stocks with current or recent manufacture stocks.
Your gun could be older than the grips it's wearing.
