Only 2,000 Greene carbines were manufactured by the Mass. Arms Co. in the mid-1850s for the British for use in the Crimean War. All but a few hundred reportedly being scrapped for parts later, with few seeing actual military service. They differ from the American type in the larger caliber, with the use of Queen Victoria's "St. Edward's Crown/VxR" cipher behind the hammer on the lock, the British proofmarks, shorter barrel, hexadecagonal section ahead of the rear sight, sling ring on the lower tang, and the use of steel for the buttplate and patch box instead of brass. This example has standard markings and features including a "1" cartouche on the buttstock and "sold out of service" mark on the barrel.

Very fine, 70% plus original blue finish and 75% of original case colors with the balance a smooth grey patina. The wood has some scattered minor-moderate dings and scratches and clear cartouches. A spurious U.S. mark is visible on left side, rear buttstock. Mechanically excellent.
