This gun is a great example of a restamped fraud. The gun has been heavily buffed and then a very poor job of restamping was applied. The stamped sderial number - 10904 - would date the gun to 1874. However the components are mostly in the 1890's. On the right side of the frame - just above the trigger guard - a banner is engraved. The heavy buffing has removed most of it, but I have included a sketch based. Perhaps somebody will recognize the banner. I expect it was applied by a dealer. Although I collect a number of authentic originals, I enjoy tracking down some of the poor restorations and frauds I have found.
