One of approximately 2,000 manufactured circa 1855-1857 on contract with the British for use in the Crimean War. All but a few hundred were reportedly scrapped for parts later, with few seeing military service. Chambered for use with .577 caliber, with blade front and folding ladder rear sights, Queen Victoria's "St. Edward's Crown/VxR" cipher marked on the lock, British proofmarks, hexadecagonal section ahead of the rear sight, sling ring on the lower tang, and a steel buttplate and patch box. Unit markings stamped on the right of the buttstock consisting of an upside down "1" above "G/10/RDMR". These markings are believed to possibly be either for the Royal Devon Mounted Rifles or the Riversdale District Mounted Rifles.
