Colt's five shot "House Pistol" was part of the House Model line that debuted in 1871 and was one of Colt's first two cartridge revolvers. Only 2,150 were produced in this configuration and manufactured circa 1874-1876. This example was produced near the end of production. The final serial number is estimated to have been 9952, suggesting this revolver was produced in the final months of production. It has the standard markings and features including matching serial numbers on the barrel, butt, and grips. This specific revolver is pictured on p.186 of "The William M. Locke Collection" by Frank Sellers. Provenance: The William M. Locke Collection; The George S. Lewis Jr. Collection
