Only around 350 to 400 of these second model rifles were manufactured in the 1850s by Parry W. Porter of Memphis, Tennessee, and New York City. The Second Model is identified by the serial number range of approximately 300-679 as well as the circular turret magazine cover. With most second models usually missing their magazine cover, this example has a professionally made replacement (serial number matching) turnscrew secured cover affixed. "ADDRESS/P.W. PORTER/NEW-YORK" and "P.W. PORTER'S/PATENT/1851" marked on the upper left barrel flat in reference to Porters patent number 8,210 of July 18, 1851. It has blade and notch sights offset to the left, a serpentine loading lever, smooth buttstock with standard rifle buttplate, and the matching serial number is marked on various components including the removable turret magazine. "GDM" (George D. Moller) collection initials marked at the toe of the stock. Includes a "crown/B-P" marked bayonet and a broken bayonet collar off of the right of the muzzle end of the gun. At the time of writing this description, no other examples of the limited surviving P.W. Porter rifles are known with a provision for mounting a bayonet. Provenance: The George Moller Collection
