Designed from the ground up by John Hall including the machinery and methods of manufacturing, these rifles were very innovative for the time and are considered the first firearm to successfully achieve true parts interchangeability, the first nationally adopted breech loading firearm, and also the first breech loading firearm to see widespread military use. In 1826, a government commission disassembled 100 Hall rifles, mixed up the parts, and re-assembled them on newly received stocks with no reported problems and thus confirmed Hall's success. This example has been converted to percussion from its original flintlock configuration, which was commonly done by the Confederacy during the Civil War. Standard offset blade and notch sights, button head ramrod, "J. H. HALL/H. FERRY/US/1833" marked on the breechblock.

Fine as period converted to percussion, retaining 85% original brown finish on the barrel, frame and fittings, and strong casehardened finish mixed with smooth brown and gray patina on the breech block showing clear markings. Stock is also fine with some light handling marks, a few minor cracks around the buttplate, some scuffs concentrated to the left of buttplate tang, and distinct edges overall. Mechanically excellent.
