-- Well, that's part of the problem, as the gun is one of the unmarked models. Other than the H&R name/address there is only .32 S&W CRTGE stamped on the left side of the barrel. This may end as a curious garage wall ornament. It's my understanding these were made around 1904-1907, what I believe they called the "NEW" model, but there are no markings to go by.
--External, it resembles the Police, the Premire, or the Hammerless (except it has a hammer). The internals are different, so I'm at a loss of a proper description.
