This is a really nice Gustav Young engraved 1851 Colt Navy Revolver with an inscription on the back-strap reading, "Leiut. Jas. Walker", obviously for James Walker. A friend of mine that leaves tons of bids at every hoping to catch something falling through the system bought this recently. In my opinion, he stole it, so I didn't mind paying him a reasonable profit. The gun is really sharp and crisp and retains 20%+ original blue, mostly on the barrel lugs and in protected areas. A whole slew of engraved guns in this a serial range headed South just prior to the breakout of the Civil War, and I'd expect that Lieutenant Walker was a Confederate Officer. How to prove it would take some doing and only with iron-clad documentation from a will or something of that nature.
