Model 1816 muskets were primarily used in conflicts with various Native American groups after the War of 1812 and were also used into the Mexican-American War era and the Civil War, generally after being converted to percussion. Features a top mounted bayonet stud, brass blade front sight located on the rear strap of the front barrel band, "P24" marked on the front strap of the front barrel band, serial number "E 31" on top of the breech, "P/eagle head/V" proofs on the left of the breech, "1829" dated barrel tang, "SPRING/FIELD/1829" on the tail of the lock and "eagle/US" at the center, circled script "ET" (Elisha Toby) cartouche on the left stock flat ahead of a circled script "EB/3" (Elizur Bates) classification cartouche which would have been marked in the 1840s when this musket was inspected for worthiness of conversion to percussion (remains in its original flintlock configuration), "ZC" ahead of a circled script "JS" cartouche behind the lower tang, and a "US" marked buttplate tang.

Fine, retaining 40% plus original brown finish on the barrel and fittings, 30% plus original casehardened finish showing at the center of the lock, scattered mild surface corrosion on the balance overall, and sharp markings in the metal. Stock is also fine with defined edges, scattered light scratches and dents, a few chips, a small crack ahead of the lock, and crisp cartouches. Mechanically excellent.
