Greeting all. I have been enjoying your forum as a guest for some time now. I am amazed at the amount of knowledge that is represented here. I have a question about an old top break double action revolver. From my research on this site it is a No 4 DA (top of barrel shows 1880, 1882, 1889; round triger guard). I am not concerned about value, but would like to know how old the gun is. The serial number is 373513 (matches all three places). My Dad gave me the gun (he is 94). It was his daddy's gun. He said that his dad carried it in his pocket everyday. I would also like to know what caliber it is. I know that it is a .38, but not sure which one. My Dad has always said that it is a .38 Short, but I cannot find anything that says they manufactured these pistols in a .38 Short ( I am guessing that would be a Colt Short). He says that the bullets he had for it had S&W on the bullet. Any ideas?
