This Japanese matchlock is 49 3/4 inches in length and has the distinctive stock with short butt. The unique brass Japanese matchlock action has a serpentine that is cocked against an external leaf spring and released by a stud trigger on the lower rear portion of the stock. The flash pan is shielded by a brass cover that is manually rotated to expose the priming powder. The barrel is round with a flat top and flared octagon muzzle with a notched front sight and a raised rear sight (base only). The top of the barrel is stamped with Japanese characters ahead of the rear sight and has a silver inlaid Japanese Mum behind the rear sight. The stock is pinned to the barrel with three pins and "2360" has been scratched into the stock ahead of the flash pan.
