This is a Civil War Colt 1860 Army revolver and is serial number 137725 and was made in 1863. The cylinder is not matching, probably a group blanket swap mix up when cleaning them after a skirmish. It has nice amounts of blue remaining. The frame still has 35% case colors. The mechanical function if very good, crisp and tight. The bore is very good, bright and shiny. There are many inspector stamps on various parts. The grips must have been lightly sanded so no grip cartouche visible. This is a solid Colt 1860 and would be a very good shooter.
