Hello. I have a smith and wesson revolver double action 2". I don't have any paperwork or id for this gun. I was looking for some help to figure out what it is. The markings on the bottom of the handle between the wood grips are 5D30789. It says .38 S&W. spl on the barrel. Made in USA marcas registradas springfield mass. With the cylinder open under the barrel the markings are MCD 10-7 C14 22494. These are all the numbers on the pistol. Its in really good shape and I know its older. Just not sure how to date it. Thanks a lot. I can post pictures if needed.
