Re: Buffalo bill handgun
This is quite similar to the Eli Whitney revolvers of the late 1800s. If it is, Dixie Gun works may have parts for it. You can contact them and they may be able to help you. Your gun was probably made around 1875 or so and if you do manage to find the parts to make it shootable, don't shoot anything but CB caps in it. It would probably chamber .22 shorts, but it might put schrapnel in your eye. I don't think it has any real value, but you should avoid doing any cosmetic other than lightly cleaning and oiling it.
