An extremely rare revolver. Chambered for .44-caliber percussion. Has a 7.25" octagon barrel, with an integral loading lever that pivots to the side instead of downward. Hammer is mounted on the side and there is a pellet priming device located on the backstrap. There is only one nipple on the breech that lines up with top of the cylinder. Cylinder is unfluted and holds 6-shots. Finish is blued, with walnut grips; frame marked "Patented April 19, 1859". There were less than 12 manufactured in 1859. It would behoove one to secure a qualified independent appraisal if a transaction were contemplated. Due to rarity, listed values are speculative.
