Late 1972 early 1973. You´re good to go with any 38 sp +P ammo from a reputable manufacturer. All K frames are. +P+ is not a SAAMI spec and thus of unknown values, specially from dubious manufacturers. You might also find this article by Saxonpig in the Smith and Wesson forum quite informative on the subject.
