I have a S&W22 revolver and would like help ID'ing it. It has a number # 135** stamped into the frame and crane. It also has a different number stamped into frame on bottom of grip. Which location is the serial number? I have a pic of gun in the gunsmithing section. My apologies for posting in two areas, but thought I might get more info in a section more dedicated to this era of manufacture. Thanks for any help. http://smith-wessonforum.com/s-w-smithing/102413-k-22-outdoorsman-parts.html
