The Peterman rifle-musket is described on pages 569-570 of George D. Moller's book "American Military Shoulder Arms Volume III", with this exact musket photographed on page 570. The book states, "A single rifle musket with lock marked 'PETERMAN' over 'PHILa' is known. It is speculated that it is either a prototype or experimental arm made by Abraham Peterman who was located at 131 Walnut Street in Philadelphia. The reason it might be an experimental arm is that it has a highly finished smooth bore that tapers from .555" at the breech to .560" at the muzzle, and it might be an unfinished experiment in tapering the land diameter rather than the groove diameter, as was standard in U.S. and British rifled muskets. The arm's mountings are similar to those of the .54 caliber rifle muskets made by Henry Deringer. All metal components are finish bright except for the blued nipple and case-hardened bridle, tumbler, and sear. Most of the metal components are stamped with a single letter and numeral." "GDM" (George D. Moller) collection initials marked at the toe of the stock. Includes a US socket bayonet marked "136", leather sling, and wood tampion. Provenance: The George Moller Collection

Very fine, retaining most of its bright surfaces with scattered light spotting, patches of light pitting, and sharp markings on the lock. Stock is also very fine with some dents and handling marks, a chip at the front edge of the left flat. Mechanically excellent. Included bayonet is very fine.
