George P. Foster of Taunton, Massachusetts, manufactured these Porter patent turret rifles in the 1850s, showcasing a number of impressive features. They are in essence lever action revolving rifles featuring vertically oriented turrets. Features an automatic percussion primer built into the lock plate (absent spring mechanism), blade and adjustable notch sights offset to the left to clear the turret, the address and patent markings "ADDRESS P.W. PORTER/NEW-YORK" and "P.W. PORTER'S/PATENT.1851." on the upper right barrel flat, matching serial number "108" marked on various components including the removable cylinder, and a smooth straight wrist buttstock.

Very good plus, with a very fresh appearance, exhibiting a mix of smooth brown and gray patinas, some scattered light surface freckling, some patches of light pitting, and defined markings and edges in the metal. Stock is very good with scattered dents and scratches, and defined edges. Absent rear sight elevator. Absent primer feed mechanism spring, otherwise mechanically fine. A desirable antique American firearm!
