European, mid-19th century. Unmarked. Iron shaft (barrel) and grip, with tan paint overall. 37 1/2” length, with 28 1/2” tapered barrel, about 12 bore. Muzzle loading, the barrel unscrews to reveal the breech with central percussion nipple. The handle with concealed trigger with nail lip tip which unfolds to fire. The mechanism is “cocked” by pushing the central “hammer” in the grip tube which released by the trigger, strikes the percussion cap. Mechanically excellent. The painted surface with wear and chips.
