This interesting ring pistol was designed and manufactured by master gunsmith Francis C. Lebeda. It uses a percussion system and is convertible from an over/under style derringer to a five shot revolver. Similar style pistols were common throughout the world in the 19th century where they were often used as indoor target pistols. The over/under barrels are capable of firing a .240 caliber round ball using a number 209 primer. This ring pistol also features light engraving on the left side, bottom, and top, as well as the maker's marks on the sides of the barrel block. Includes a tin Jack Daniel's playing card case with a Lebeda plaque on the bottom, an unopened package of playing cards, and an extra cylinder that appears to be in .177 caliber.
