The Model 1819 Hall was the first U.S. military breech loading firearm issued in large numbers and also the first firearm manufactured with totally interchangeable parts. It took Hall some five years to get the proper tools and machinery assembled to produce the rifles, but 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. Though they suffered from gas leak and other issues common to early breechloaders, the Hall rifles and carbines remained in use through the Civil War. This rifle has the standard offset blade and notch sights, "J. H. HALL/H. FERRY/1838" marked breechblock, "JG" stamped behind the trigger guard, and a proper button head ramrod.

Exceptionally fine with 85% plus original brown lacquered finish, muted original case colors on the breechblock, smooth gray patina on the faded areas, and generally minor age and storage related wear overall. The rifles does not appear to have been used. The stock is very fine and has smooth lightly oiled finish, some scattered dents and scratches, small flakes of wood absent at the top buttplate tang and left corner at the top of the wrist, and generally light storage related wear. Mechanically excellent.
