How do I find the value of a smith and Wesson 22LR pistol with CTG markings?

Hello, Your question on a S&W can be answered if more information was known about the Smith in question. You may wish to check to see which model you have by looking on www.ArmChairGunShow.com . I am not connected to this site but Jim Supica, who writes the S&W book of values, is one of the best in helping with which model you have.
