Colt referred to this as the "New Model Revolving Pocket Pistol," and collectors often refer to them as "Root" revolvers after Colt's superintendent Elisha K. Root who took over as company president following Samuel Colt's death until Root's own passing in 1865. Given their sleek design which departs heavily from the usual Colt percussion revolvers along with their limited production and several production variations, these revolvers have long been popular with collectors. This exceptional example was manufactured in 1865 and is the Model 6 variant. It has a brass post front sight, "ADDRESS COL. COLT/NEW-YORK U.S.A." on top of the barrel, loading lever with round arm, the cabin and Indian fight scene on the cylinder, push button release for the cylinder pin, and matching serial numbers visible on the barrel, cylinder, and butt. It comes in a fitted case with a cap tin, dual cavity bullet mold without a sprue cutter, small eagle pattern flask, and a screwdriver.

Excellent with 97% plus of the bright original high polish blue finish, 95% vibrant case colors, and nearly all of the bright original niter blue remaining and only minimal light fading on the capping cutout and light edge wear. The grip is also excellent and has only light handling and edge wear. Mechanically excellent. The case and accessories are fine with some broken dividers, a crack in the lid, and general mild wear. This is a stunning example of Colt's Model 1855 Pocket from the final year of the Civil War.
