American made single-shot pistol that were manufactured from 1863-1890. The bore is excellent, bright with strong rifling. The metal has completely turned a brown patina. The grips are near excellent with some minimal wear. The pistol is marked with Meiji-period Japanese registration/importation markings on the left side of the barrel. During the reign of Emperor Meiji, the samurai were abolished and replaced with the Imperial Japanese Army. Overall an excellent example and interesting Japanese import.
