Nice thread, impressive collection!!
I have one 14-2 close in Sn to the OPs 1964 gun. My SN is K5513XX. Its also marked Mod 14-2 with the SN in the crane area. No markings on cylinder or barrel. Has target trigger and hammer, its wearing non marked diamond targets. I have no box for it or prior history. Mine is a shooter grade gun and a darn good shooter at that. Makes me look like I can shoot and I'm a bad shot
