This rifle is pictured and discussed on pages 352-355 of "U.S. Military Shoulder Arms, Volume II: From the 1790s to the End of the Flintlock Period" by George Moller and has his small "GDM" collection mark by the toe. He uses this rifle as his example of the 1807 Contract Rifles and states Henry DeHuff delivered rifles for the contracts in association with Jacob Dickert and other Lancaster area gunmakers. A very similar example is pictured on page 606 of "Flayderman's Guide to Antique American Firearms and Their Values" (9th Edition) in his section on the U.S. contract rifles. The rifle has traditional blade and notch sights, "Dehuff" signed on top in script, "US" on top at the breech, "67" followed by the sunken "eagle head/P" and "P" markings on the upper left at the breech, a simple border design at the edge of the breech, imported Germanic style lock with gooseneck cock, and frizzen and frizzen spring screws fastening from the inside, brass furniture including a plain patch box with three screws in the finial and heel release button, simple cheek rest, and wooden ramrod. Provenance: The George Moller Collection
