The rifle features double barrels that revolve, each having it's own bolster, nipple and iron sights. One barrel is rifled, the other is not. One side of the barrels has a solid rib with maple panels with brass tip. The reverse panel accommodates the wooden ramrod. The top of each barrel flat is marked "H.D. * PHILADELA". The lock plate is a simple leaf type engraving. The brass patch box and lower buttplate tang are engraved and the side plate has a thumb rest. The buttstock is tiger stripe maple with a brass trigger guard and crescent buttplate, raised cheekpiece with silver star inlay, silver shield inlays on both sides of the wrist and single trigger.
