I am helping a friend's widow sell her late husband's collection. She has a 5 shot, 3 1/4" barrel S&W .38 CTG, serial number 40312. The barrel lists patterns of Aug 98, Dec 99, Oct 01, Feb 09 and Sept 09. I'm at a loss for its value or even the ammo it takes. The buleing is good a d it seems in fine working order. Does anyone know what she has or it's approximate value? Thanks in advance for your help!
