I just picked up an older .22 and am trying to find model. 5 screw blued, 6 in barrel sn k415xx. It has full barrel rib and adjustable sights, no model no.
Welcome to the Forum. It appears, from your info., that you have a postwar K 22 Masterpiece , made circa 1947-48. If 1947, it will say on the right side of the frame " Made in USA." If 1948, It will have 4 lines of stampings, with "Made in USA" and Marcus Registrada, etc. " S&W did not use Model number designations until 1957, so your gun was referred to as a "K 22 masterpiece" in the S&W catalogs.
