This very scarce Colt Model 1860 Army was manufactured in 1867 within the known late "London" range and has the "-ADDRESS COL. COLT LONDON-" barrel address, iron grip frame, and "L" by the main serial numbers that usually indicates the revolver was destined for Colt's London depot; however, it lacks London proofmarks suggesting it may not have went abroad despite the factory's original intentions. The other markings and features are standard including all matching visible serial numbers.
