I sent a email with my S/N which starts with 2K to David Valenze at Smith & Wesson and he emailed me back that based on my S/N it was made in 1970. You can also go to Smith & Wesson web sight and fill out a request to have them send you a letter but it cost $50.00. I used the email it did not cost plus I kept a copy and put with my revolvers other paper work. Here is his email address just sent shot request with Model and S/N.
