Active in the late 19th and early 20th Centuries, A.O. Niedner played a role in the development of the Patridge front sight and the 22 Long Rifle cartridge. Built around a Smith & Wesson New Model Number Three (produced 1887 - 1910), the cylinder has been removed and replaced with a fixed chamber and solid block, marked "A.O. NIEDNER/ MALDEN, MASS." on the left side, with the standard one line barrel address on the rib and "+44 S.&W. CTG+" marking on the left side (chamber is shorterr than that of a 44 S&W, 44 Russian fits in the chamber). Fitted with a very wide Patridge front sight and a adjustable notch rear, casehardened hammer and trigger guard, adjustable stop screw, and a contoured and checkered right handed thumb rest target grip. Matching numbers on the barrel, latch and butt.

Refinished, with 85% of the blue, showing a flat gray patina concentrated on the grip straps, minor muzzle and high edge wear and scattered light handling marks. Bright colors are visible on the casehardened parts with most remaining. Grips are very good as custom, with a small chip on the right panel, brass insert near the butt of the right panel, light handling marks and sharp checkering. Mechanically excellent.
