No way to answer without the serial number. If you call S&W with the sn, they can help you.

The Smith & Wesson revolver with serial number K 241205 was manufactured in 1956. This serial number falls within the range of the Model 10 revolvers produced during that time. Smith & Wesson typically used a letter prefix to identify the manufacturing year, and the "K" prefix indicates it is a K-frame revolver from that period.
The Smith and Wesson model K14-3 was produced from 1947-1982. You would need to write into Smith and Wesson with the model and serial number. They can pull the date and send it back to you.
