I don't know the model number, but size wise, it is sorta between a J and K frame best I can tell. Maybe closer to J frame size. It has adjustable sights, six shot cylinder, and 3" barrel. Grips are factory original and beautiful. Not a flaw on the gun. It looks unfired. I bought it a few years ago and put it in the gunsafe. I love the caliber and I have another revolver in 32 Long that I shoot. this one has been too pretty to take out. It is the tightest revolver I have ever seen. I think it is unfired but can't prove it. Price is $300. Wallace in Warner Robins 478-918-5392
