Manufactured in 1877, the standard two-line address on top of the barrel, desirable "COLT NEW 41" etched panel on the left. There are British proofs on the bottom of the barrel and on the cylinder. The left of the frame is marked "41CAL C". The full serial number is on the left of the grip frame and bottom of the barrel, and the partial serial number "570" is on the rear face of the cylinder. It is fitted with smooth rosewood grips, the right panel having "IW75" carved on the inside.

Very fine, retains 75% of the original blue finish and 85% vibrant case colors with the balance having thinned to mostly a smooth grey patina with a crisp etched panel. The grips are fine with some scattered light handling marks. Mechanically excellent.
