This is an incredibly rare martially marked Colt Model 1849 Pocket revolver; reportedly one of 50 purchased by the union Defense Committee U.S. Navy in 1861 in the 203000 and 204000 ranges. It has the rather rare two-line "-ADDRESS SAML COLT/HARTFORD, CT.-" barrel address and a naval anchor mark. Cylinder with inspector marks "P/GG" (Guert Gansevoort, New York Navy Yard Inspector). "UDC" (Union Defense Committee) on the butt. One letter inspector marks on various parts. Matching serial numbers on the barrel lug, cylinder, frame, trigger guard, and butt. Matching partial number "4482" on the loading lever, and in black ink on the back mortise of the one piece grip. In April of 1861, The Union Defense Committee was established directly after the attack on Fort Sumter at the outbreak of the Civil War in both Chicago and New York to facilitate the equipment and outfit of regiments of volunteer militia. Active aid was immediately put towards a variety of arms including handguns, shoulder arms and swords. The Union Defense Committee aided the Union Navy with the steamship USS Quaker City and supplied it with a variety of arms in 1961. The Quaker City, outfitted with a 20-pounder Parrott rifle, was one of the most active and feared blockaders of the Civil War, and there is a very good chance these Colt 1849 Pocket revolvers were on board.
