20 Shot Josselyn Revolver:

Thank you ' Antique Guy ' for your submittal.
This is a unique single action revolver patented by Henry S. Josselyn in 1866. There is very little Information on this firearm. It was designed to fire twenty rounds without reloading simply by cycling a new round on the flexible chain after each fired round. One of these handguns can be seen at the Smithsonian Institution.
