.60 caliber. 36" pinned three-stage octagon to round barrel. SN: NSN. Oxidized metal, brass and iron furniture, full-length walnut stock. Percussion altered flint lock with commercial percussion hammer and drum bolster. Lock marked with the "{Circle-Fox}" trademarks, as is the top flat of the barrel. Breech with post-1813 Birmingham commercial proof marks. Mounted with a German silver "Indian Chief" wrist escutcheon, three-screw brass dragon motif serpentine side plate, screwed flat brass buttplate, oversized iron triggerguard and a sheet brass reinforcement band near the forend tip.

A nice example of a 1st half of the 19th century "Chief's" trade gun that had its working life extending into the percussion era.
