It was probably a "lightweight" which was an option available for Regular frame guns prior to the FW frame. Does anyone know what the "lightweight" features actually consisted of? Was it just a combination of finer struck barrels and lighter wood? I think I read in Brophy that it was available for grades 2 and up and included "Nitro Steel" barrels. Brophy also shows a good photo of the Annie Oakley engraved gun.
