The M1819 Hall rifle was the first breechloader adopted on a wide scale by a military force (the British Ferguson predated it, but was only made in small numbers). The Hall stayed in production on and off for several decades, being made in many configurations. This particular one is an 1836 pattern smoothbore Hall carbine, with a retracting spike bayonet.
This is the last of the videos I had the chance to make at Rock Island, and they are all going to be up for sale at the Premier auction this coming weekend – along with a couple thousand other guns. I hope you enjoyed these videos, and hopefully I will have the opportunity to do this again at another future auction!
