U.S. Springfield Model 1842 muskets were manufactured at the Springfield Armory between 1844-1855. This model is significant as the last U.S. martial smoothbore musket, with known use in the Mexican-American War (April 25th, 1846–February 2nd, 1848) and the U.S. Civil War (April 12th, 1861 – April 9th, 1865). "Eagle and shield/US" marked center of the lock, "SPRING/FIELD/1847" at the tail of the lock, "V/P/Eagle head" proofs at the left of the breech, "1847" dated barrel tang, oval script "RC" and "JW" inspection cartouches on the left stock flat, and a "US" marked buttplate tang.

Fine as covered in a coat of old dried grease with sharp edges on the lock and pronounced markings in the metal. Stock is also fine with defined edges, scattered scratches and dents, and crisp cartouches. Mechanically excellent. This is an attic fresh example of a desirable Mexican-American War era U.S. Springfield Model 1842 musket!
