H&R Arms 5-shot revolver
I am looking for any information with regards to my great-grandmothers pistol which I have inherited. The hammerless 5-shot revolver has a 2" barrel, break top, auto ejector, pearl handle, and is nickel(?) plated. 73945 is stamped on the butt of the handle. H&R Arms Co. Worcester, Mass is stamped on the top of the barrel. 945 is stamped on the interior of the revolver. The pistol is in very good condition. When was it manufactured, what caliber is it, and what is it worth? Any information would be greatly appreciated!
