1856; serial number 6475
Manufacturer: Colt's Patent Fire Arms Manufacturing Company
87.118.20.1

The most extensively cutaway Colt percussion revolver is this Model 1855 Sidehammer Pocket. Cutaway, or skeleton, arms were used to demonstrate the mechanics and special features found on Colt firearms. Serial number 6475 is superbly machined to reveal the inner workings of the barrel, rammer, barrel lug, frame, cylinder, and grips. The chambers in the cylinder received special attention. One chamber is slightly machined, another is machined approximately in half, and two other chambers are cut into entirely. Despite its impressive design, the Sidehammer was the least successful model introduced by Colt’s Patent Fire Arms Manufacturing Company during Samuel Colt’s lifetime.
