Henry made that one. I doubt he was happy with the use to which his product was put.
When I first saw that pistol many years ago, the hammer screw was broken off in the tumbler and the head missing. Apparently some genius at the NPS decided to have the screw replaced while Ford's Theater was closed for renovation.
That did not go unnoticed and the result was a lot of finger pointing and questions about whether the gun was actually the original or if someone sold the original to a crooked collector and substituted another gun. That is how the FBI got into the act, asked to try to determine the truth.
Unlike the FBI, I had only pictures to go by, but concluded, as did the FBI, that the gun is the original, just with the hammer screw replaced. But in some circles, there is still controversy.
