I inherited a . 38 special, and I was wondering how old, and what it's appraised at. It's a Smith and Wesson .38 special ctg with a 4" barrel. The serial # on the bottom of grip is 405155, same as cylinder. There is another serial# 50510. The dates on top of the barrel are Oct. 8, 01, dec. 17, 01, feb. 6, 06, sept. 14, 09 and dec. 29, 14. Can anyone tell me how old, and/or how much its worth?
