Hey all. I have been offered a chance to buy a nice older 38 special and don't know what model it is. There for I have no idea what to offer for it. It is a blue approx 4" tapered barrel with grooved rib and a blade front sight. There are no markings save the description on the right side of the barrel, 38 Smith & Wesson Special ctg. Anyone have a pic or idea of what it is?
