The "Root", as it is commonly known, was the only solid frame percussion revolver Colt manufactured. The Model 6A is one of the rarer variations. This one was manufactured in 1864 and has a brass post front sight, "ADDRESS COL. COLT/NEW-YORK U.S.A." barrel address, British proof and view marks, the stagecoach cylinder scene, and matching serial numbers on the barrel, cylinder, and butt. It comes in hardwood case with a London addressed label with "DIRECTIONS FOR USING/COLT'S NEW MODEL PISTOLS, RIFLES, CARBINES, AND SHOT GUNS," bore rod, Eley Bros. cap tin, L-shaped combination tool, blued Colt patent bullet mold, oiler, Dixon & Sons bag shaped powder flask, bullets, and a key.

Fine with 30% plus original blue finish, traces of original case colors, gray and brown patina on the faded areas, mild scratches and dings, light oxidation, and some edge wear and rub marks on the otherwise fine grip. Mechanically needs work: the trigger has to be manually reset. The case is very good with a fine original interior label, moderate storage wear including some cracking. The accessories are fine and have mostly storage type wear.
