Serial number 187357. Made 1870. 44 caliber with an 8” barrel. Beautiful gun that is factory engraved. Barrel has 85% of the original blue finish. Very good case colors on the frame. Grips are excellent. Cylinder still has virtually all of the cylinder scene and most of the original blue. Both case and accessories are very fine. Very rare to find a later Factory engraved Colt 1860 like this with blue finish. Most of these guns were finished in Nickel. This would be a very hard set to improve upon!
