William Defibaugh (1814-1891) was a gunsmith active from the mid-19th century well into the late 19th century in Monroe Township, Bedford County, Pennsylvania. The barrel is signed "W*Defibaugh*" on top of the breech section with some dot accents and has seven groove rifling, traditional dovetailed blade and notch sights, and a pointed tang secured by two screws. The distinctive Bedford lock has no visible markings. It is equipped with adjustable double set triggers. There are lightly engraved silver inlays on the drops, wrist, and cheekpiece, and the latter is engraved with a spread wing eagle and shield motif. The furniture is brass, and the four-piece patchbox has some simple engraving. The release button is at the rear of the upper side plate. The toe plate has floral blooms engraved around the screws. The stock features incised molding, carving at the front of the flats, extended drops, relief work at the back of the wrist, and relief carved scrollwork behind the cheekpiece.

Fine with smooth brown patina on the barrel and lock, aged patina on the brass and silver, and general mild overall wear including some light oxidation and pitting. There are some flaws in the casting of the buttplate. The stock is also fine and has mostly distinct carving with some rubbing, attractive flame figure, small chips and slivers absent at the edges, a few thin cracks, a few repairs including at the front ramrod pipe, and general mild overall wear. The lock needs work/adjustments. The set triggers are mechanically fine.
