This double-barrel shotgun made for Texas Jack by James Dalziel Dougall & Sons, as a gift from Windham Thomas Wyndham-Quin, 4th Earl of Dunraven. The gun is serial number "3303" on the tang. An oval copper plate set in the bottom edge of the European walnut straight grip buttstock is engraved: "From / Earl Dunraven / to / Texas Jack / 1874."

This gun was in the collection of Nate Salsbury, Buffalo Bill Cody's partner in the Wild West Show, and is now part of the permanent collection of Yale University.
