The gun has the stock style and furniture of a Brown Bess musket but lacks government markings and is smaller caliber, lighter built, and shorter. The lock has no internal or external bridles and is marked with a rendition of St. Edward's Crown (no "GR"). The barrel has a bayonet stud on top near the muzzle and "FC" on the left near the breech. The buttplate has "13" by the heel. The bayonet is marked "HARPER/& Co" and "O." A collection marking is on the trigger guard.
