I just bought a S&W model 10 from a coworker that he carried for a duty weapon in the early 80's. I would like to see if anyone can help me with when it was made. I know he said he had bought it used at the time. It is a smith modle 10-6 the searial number is 53233 and has R6 below it. This is stamped on the cylinder frame. Any help will be greatly appreciated.
That looks like an assembly number. The serial number should have a "C" or "D" prefix or a number/letter/number (ex. 4D8901). It will be located on the underside of the grip butt. If the grips on it cover the bottom of the grip frame you will need to remove them to see it.
