Welcome to the forums from the Wiregrass, Doug! It was made in 1976 and has the target hammer and trigger. It has some finish problems probably due to use and that will lower the value. I would put it at $500-600 around here.
Thank you guys again I will put some rounds thru it and in my night stand in case someone makes that terrible decision to enter my home one night with ill intentions! I be back with more I gotta several of papaws old s and w revolvers I'm I'm dieing to learn about thanks God bless!
That one has got nice target stocks with the "football" speedloader relief too. Nicely grained wood.
Value is highly dependent on local market. I think the $500-$600 range is a reasonable estimate, but it might fetch a little more or a little less depending on how many collectors and the availability of vintage S&Ws in your local shops.
