1819 Hall breechloading flintlock POV firing

Original Model 1819 Hall flintlock rifle made at Harpers Ferry in 1838. This rifle is .54 caliber and retains a surprising amount of original finish, suggesting it was probably never issued. These rifles were the first real wide-scale adoption of breech loaders. In testing, they were both faster to load than the standard US muskets, and more accurate than the standard US rifles. They are also notable for being the first instance of true machine-made interchangeable parts.
