Hope I'm in the right section here. My older brother has gone to a retirement community, and he passed along a Smith & Wesson revolver to me; I'd like whatever information you guys will provide me. I think it's a Model 30; there's no model number present on the crane. It's a three-screw revolver; serial number is 572xxx. The barrel is marked Smith & Wesson 32 Long Ctg. The barrel is 2-inch; sights are fixed. Condition is very good; I admit that's a subjective call, but it shows very little wear or handling. Thanks in advance for anything you can provide.
