This is a rare example of a U.S. Harpers Ferry Model 1842 Hall saddle ring carbine, one of approximately 1,001 manufactured c. 1842-1843, and the last carbine manufactured by Harpers Ferry. These were all sent to the 1st U.S. Dragoons and saw hard use in the western campaigns of the Mexican-American War, contributing to their extreme scarcity today. The 1st Dragoons were part of the Army of the West (1846), commanded by Stephen W. Kearny, which played a prominent role in the conquest of New Mexico and California. This example was period altered to a rifled bore from its original smoothbore. Features a brass blade front and iron V notch rear sight. Brass barrel bands, trigger guard, and buttplate. Inspector initials "P.M." marked on the right of the breech, "H. FERRY/US/1842" marked on top of the breech block, and "M" marked behind the lower tang. "GDM" (George D. Moller) collection initials marked at the toe of the stock. Provenance: The George Moller Collection
