The Porter Turret Rifle (2nd Variation) is a rare .50 caliber lever-action firearm patented in 1851. Unlike axial revolvers, its radial turret design posed a significant chain fire risk, though the second pattern introduced safety improvements like flash guards and a grip safety. It features a 9-round capacity, 26-inch barrel, and an innovative automatic priming magazine.
The Cochran Turret Revolver, a rare 7-shot, .38 caliber antique firearm, featured a unique perpendicular cylinder rotation. Inventor John Cochran, a mechanical prodigy, developed this design in 1837, contracting C.B. Allen for manufacturing. Despite its innovative under-hammer action and manual indexing, safety concerns like chain firing limited its success, with only about 150 units produced.
