The Colt New Line was a single action pocket revolver introduced by the Colt's Patent Fire Arms Manufacturing Company in 1873.
It was, alongside the Colt Open Top Pocket Model Revolver (1871), one of the first pocket metallic cartridge revolvers made by the company.
[2] When the Rollin White patent for metallic cartridges firearms manufacture expired (c. 1870) the Colt's Patent Fire Arms Manufacturing Company started working on its own metallic cartridge revolvers.
[2] Circa 1884-1886, submerged by the competitors' cheaper imitations and refusing to introduce a lower quality among its own firearms, the Colt company dropped the line and ceased production.
[2] The .22 caliber version was equipped with a 7-shot cylinder.
