Make: Japanese (Murata)

Model: Murata Shotgun Conversion

Serial Number: 223

Year of Manufacture: Late 19th to Early 20th Century (C&R Eligible)

Caliber: 28 Gauge

Action Type: Bolt-Action, Single-Shot Shotgun

Markings: The top of the chamber is clearly marked "28". The left side of the chamber is marked with serial number "223". Japanese characters appear clearly down the left side of the receiver. The Imperial Chrysanthemum marking originally present above the breech has been intentionally removed.

Barrel Length: 34 ½”

Sights / Optics: The shotgun retains its original brass bead front sight and fixed notch rear sight, both intact and functional.

Stock Configuration & Condition: The walnut stock is in fair overall condition, showing remnants of an older applied finish, moderate dings, scattered small chips, and heat-related finish bubbling from prolonged fireplace display. A canvas buttpad is fitted to the stock. Despite cosmetic wear, the wood remains structurally solid and serviceable.

Type of Finish: Originally Blued (now Plum-Brown Patina)

Finish Originality: Original (no finish remaining)

Bore Condition: The smooth bore exhibits moderate pitting with scattered oxidation throughout but remains relatively semi-bright. In this writer’s opinion, the bore rates approximately 7/10.

Overall Condition: This Murata shotgun retains no original blued finish, having instead developed an even, dark plum-brown patina throughout. The metal surfaces show minor pinprick pitting and scattered oxidation staining, consistent with prolonged storage and exposure. A crack is present at the top rear edge of the bolt piece, though this does not significantly impair mechanical function. Screw heads have moderate tool marks but remain usable, and all markings, though somewhat softened, remain visible. Overall, the firearm is in Fair to Good condition.

Mechanics: The bolt operates stiffly but functions correctly. Mechanical components appear complete and intact. As with all vintage firearms, a thorough inspection and cleaning are recommended before firing or operational use.

Box, Paperwork & Accessories: None.

Our Assessment:
The Murata shotgun conversions represent a unique and fascinating piece of firearms history, reflecting Japan’s transitional period from military arms toward civilian usage in the early 20th century. Initially designed by Major Murata Tsuneyoshi as bolt-action military rifles, these firearms later found civilian use as shotguns after being adapted from their original military configuration.

This particular Murata shotgun, chambered in 28 gauge, retains matching serial numbers, distinct receiver markings, and clear historical significance despite the intentional removal of its Imperial Chrysanthemum. Its extensive patina and oxidation, along with a heat-affected stock finish due to prolonged fireplace exposure, add to its character and authenticity.

Collectors of Japanese historical firearms, unusual shotgun conversions, or Curio & Relic firearms will find this Murata shotgun to be an intriguing and historically significant addition to their collections.
