44 RF cal. 24 inch round barrel with full mag and rifle style butt. Later gun in the 158k serial range with the steel forend cap and steel butt plate. Metal has been cleaned long ago as well as the brass having been polished. Traces of original blue in protected areas with the balance turning silver/gray. Brass looks to be in good shape. Original sights. The bore is surprisingly very shiny with only a couple of light pits. Wood is good fitting with no cracks chips. Smooth action.
