Less than 2,000 of these revolvers are estimated to have been manufactured in the 1860s. They are known to have been advertised at least as early as 1860 and likely designed specifically to compete with Colt's Model 1855 "Root" revolvers given it has many similarities. Given that, this is sometimes also known as the "Root Type Pocket Model." It has a small cone front sight and "E. WHITNEY/N. HAVEN" on top of the barrel, a scroll engraved cylinder, and matching serial numbers on the bottom of the barrel, back of the cylinder, butt, and back of the grips.

Very fine overall with 75% bright original blue finish, the finish loss concentrated on the frame, some small patches of light pitting and oxidation, subtle original case colors on the hammer, mottled brown patina on the faded areas, some minor dings and scratches on the grips, and general mild handling wear. Mechanically fine. This is an exceptional example of one of the rarer and more refined Whitney firearms.
