Last week I was in Cody WY at the Winchester gun show. I bought this Colt 1851 Navy with all matching serial numbers except the wedge. All lettering is crisp and the cylinder engraving stands out really good. Nearly all of the case hardening on flash guards is intact but darkened. Very little pitting in the bore, timing is good and it locks up tight!
Serial numbers show it was make in 1861.
Unfortunately someone on the past appears to have used steel wool on the side of the frame.
