PHILADELPHIA. Cal. 54 smooth bore. S# NSN. The 46" octagon to round barrel is fitted with a "V" notch rear sight and front bead. The top flat is stamped "H. DERINGER" and "PHILa." The drum and nipple have been removed, and the barrel has been reconverted to flint. A nicely engraved lock with a rebated tail is marked "H. DERINGER" and "PHILa" in front of the cock. Good-quality reproduction includes a newly welded and aged semi-waterproof pan, an old cock, a new frizzen, and a feather spring. Internal inspection reveals a new main spring and a cracked bridle. The stock of very fine curly grain maple extends to the muzzle with a brass cap and attaches to the barrel with four brass sidebolts. The stock is brass-mounted and has a trigger guard with a spur-forming grip, a slight cresent buttplate with an 8" return, and an engraved patchbox with fancy outlined sides and a pierced finial. A silver oval is at the top of the grip. Beaded ramrod pipes are brass. CONDITION: good as reconverted. Iron and steel parts mostly have a dark brown patina. The stock shows considerable hand wear overall and retains its old finish. 6" of the forepiece was replaced at the muzzle. There is a 2-1/2" piece of wood replaced between the top of the lock and the barrel tang. Bore is dark. Lock is operable. (01-24413/MGM). ANTIQUE. $3,000-4,000.
