Colt's London factory closed in early 1857 after just over three years, but many parts were transferred back to the Hartford factory where they were assembled into completed firearms. This particular example shows several oddities. It carries London proof marks marks that suggest it has been proofed as a completed firearm in England, however the high serial number, thick loading lever catch, Hartford style back strap and trigger guard, bevelled loading notch and percussion shield cap slot all point to a late forth model, produced after the period of the London Armouries operation. It is possible that either this gun was assembled in Hartford using London parts, that it has been repaired at a later date using London parts or that it has been rebuilt outside of Colt using two separate firearms.
