The 1862 Police Pocket was the last of Colt's percussion revolvers. It was a combination of the small 1849 model frame (intended for .31 caliber) and a 5-shot .36 caliber cylinder. The frame was stepped to allow the larger cylinder to fit without require any changes to the lockwork, and the result was a rather nice svelte revolver offering both reasonable firepower and relatively compact size. This particular one was exported to the UK at some point, as evidenced by its British proof marks, and also comes with the original case and accessories.
