Approximately 19,680 Model 1819 Hall rifles were manufactured between 1819-1840, and this example is one of approximately 1,200 manufactured by Harpers Ferry in the year 1837. 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. Standard offset blade and notch sights, button head ramrod, "J. H. HALL/H. FERRY/US/1837" on the breech block.

Excellent, nearly as issued, retains 90% plus original brown finish, 95% original casehardened finish on the breech block, minor handling and storage related wear, with defined markings. The stock is also excellent with a few light handling marks, a very minor small crack on the top right behind the frame, and distinct edges overall. Mechanically excellent. This excellent U.S. Harpers Ferry Model 1819 Hall rifle would be difficult to improve upon!
