I was given a 38 S&W CTG by my father who had it from his dad. I'm trying to get some info on the gun. It's chrome plated, is the 5 shot top load, hammerless with the safety grip. It has a white plastic grip with the diamond around the single pin. The barrel is 2 inches long. Serial number on the grip and under the cylinder is 213606. Any idea when this was made and what the value may be?
