My 14-3 1K745xx is 1970-71, another K frame 1K843xx is 1970, so your 1970 is likely correct. Your target stocks have a speedloader cutout and are much later vintage.Greetings all. I would like to know if a 14-3 with a serial # 1K304xx was in fact made in 1970. It has what seem to be correct stocks , but they are stamped “1983”. There is no serial number on them as there is on my 31-1. TIA.
