On this edition of Curator's Corner, John Popp joins National Firearms Museum Senior Curator Phil Schreier in the William B. Ruger Gallery to showcase one of the first breech-loading rifles in history. Before John Hall invented the M1819 Hall Breech-Loader, most rifles of the day were based on flintlock mechanisms. Schreier says this particular rifle has the distinction of being made at Harper's Ferry, Virginia in the years prior to the Civil War, though breech-loaders like it became widely used in the Mexican-American War. This historic rifle can be seen on display every day at the National Firearms Museum. Originally aired 9/16/2010.
