I have two old top-breaks that I know very little about. I'd love to know proper nomenclature, model number, and manufacture/shipping dates. The first is an H&R hammerless 5-shot 38 S&W. It has a 4-inch barrel and is nickel plated. SN is 208XX. The other is an Iver Johnson 5-shot 32 S&W with a 3-inch barrel. SN is G 282XX. I'd appreciate any help or leads anyone could give me.
