This is a really great Colt 1851 navy Revolver with full martial markings to include cartouches. The gun retains 90%+ original blue to its barrel and about 60 - 70% on the cylinder. One side of the cylinder is missing some blue where it has aged from laying on its side. Case colors are 90% and quite vivid. The grips are original and with a bit of aged wear. A wonderful government issued gun that was seldom used, probably maintained as such by an officer.
