Yeah...tried Googling, but was unable to find any pertinent info. This hypothetical cane gun is verifiably old (1900 - 1920), centerfire, rifled bore, about 44 cal, with a dark grey bone (or horn, or plastic) handle. Rotating the handle while holding the barrel will open the action for loading, and rotating a smaller sleeve in front of the handle will expose the trigger. There are no markings on this hypothetical item, other than a stamped number.
