Colt House Revolver

The Colt House Revolver (also called, in its alternate 4-round capacity model, the Cloverleaf) was one of the first metallic cartridge rear-loading revolvers to be produced by the Colt's Patent Fire Arms Manufacturing Company, in 1871. The same year, Colt's also patented the Colt Open Top, another metallic cartridge rear-loader, but in fact the Open Top production didn't start until 1872, although a pocket version of the Open Top, a completely different design, went on sales as of 1871, the Colt Open Top Pocket Model Revolver.

The Colt House Revolver was manufactured from 1871 to 1876 in two different models: the Colt House Model itself and the Colt Cloverleaf Model, the latter being the most produced of both. The House Model is also known among collectors as the Jim Fisk model or the Jim Fisk pistol, since it attained the infamy of being the gun used in the murder of James Fisk in January 1872.
