George Moller noted this as a "trade rifle." His tiny "GDM" collection mark is ahead of toe plate. The gun is certainly more plainly built than others signed by Christopher Gumpf, a gunmaker in Lancaster, Pennsylvania, from 1791 to 1834. The barrel has a smoothbore and appears to have been shortened and bored out smooth in the period. It has low profile rifle style sights, decorative floral and wavy line engraving in the midsection, "C Gumpf" signed on top, a stamp on the upper left at the breech that appears to be "CH," and a decorative dot pattern at the breech. The flat lock is signed "SWEITZER" at center (Z horizontally inverted as seen on others) and has a lightly stepped tail with simple engraving. It is equipped with adjustable double set triggers and has brass furniture. The four-piece patchbox has piercings on the finial and side plates, light engraving, "2 W H" (2 probably a J) inscribed on the lid, and a release button on the heel of the buttplate. The toe plate is an interesting design with scalloped edge and three "key-hole" piercings. Silver oval inlays are pinned on the wrist and the shallow cheek rest, and there is a pinned brass plate with wavy line and dot patterns pinned on the left side of the butt. Provenance: The George Moller Collection

Good as reconverted to flintlock configuration and shortened/altered with dark brown patina and finish on the barrel, dark bluish tone on the lock, mild pitting mainly at the breech, aged patina on the brass and silver, distinct signatures, and generally crisp engraving. The stock is fine and has repairs in the forend including eye shaped spliced around the barrel wedges, some small chips and flakes at the edges and barrel tang, attractive flame figure, and mild scratches and dings. The lock and trigger setup requires the triggers to be set before cocking, and it will drop from half-cock when the trigger is pulled. Otherwise, it is mechanically fine.
