This is an about FINE condition example of an original L-shaped combination tool produced by Colt for use with their “Army” and “Navy” percussion revolvers, including the Models 1851, 1860 and 1861. The tool is well machined steel with a blued finish and measures 3 3/16” in overall length and is 1 25/64” wide at the top. The tool combines an open-end cone wrench with recess for the tip of the percussion cone at the shorter portion of the “L” and a screwdriver arm. The screwdriver arm is 5/32” thick and 21/64” wide at its widest point and tapers to 3/64” thick and 3/16” wide at the beveled screwdriver tip. The tool also has the slightly beveled edge along the spine that is found only on the original tools and not on modern reproductions. The tool retains some strong traces and scattered flashes of the original bright blued surface finish, possibly as much as 10%-15%. The balance of the tool shows much of the original underlying dull blue still intact, although there is moderate wear and loss to the finish from handling and use. The largest areas of loss are along the sides of the round cone wrench body and along the sharp and high edges and places where the tool was regularly handled. The cone wrench itself remains fairly crisp, with some minor wear to the face of the wrench from use. The metal is smooth and free of pitting but does show some scattered freckles of surface oxidation and a few tiny areas of minor pinpricking. Overall, this is a very nice, complete and crisp tool that will be a good addition to the display of your Colt Army and Navy revolvers or to add to a cased set that is missing its original tool.
