Google "1851 aces and eights" and you'll get some hits. Apparently made by Pietta and marketed by Traditions. Also Google "Traditions 1851 aces and eights" and "pietta 1851" and you'll get better info. Best I could see, the Aces and Eights model is not made anymore. The Traditions site shows the same gun now, just without the Dead Man grips. Both are .44 caliber. Hickok's were actually engraved nickel .36 caliber with engraved ivory grips..
