The musket is one of the US 1816 pattern muskets altered to the Maynard mechanical priming system at Frankford Arsenal circa 1856-1858, with 20,000 altered for the US government and 2,000 for the State of New Jersey. The guns were also rifled during the conversion process, with the US gun fitted with long range rear sights and most of the NJ guns not so equipped.
