This interesting ring pistol was designed and manufactured by master gunsmith Francis C. Lebeda. The five-shot revolver cylinder is capable of firing a .240 caliber round ball using a primer (likely a 209 primer). This ring pistol also features light engraving on the left side, bottom, and top. Included is a blue fabric covered case. A plaque on the case has the family history of master gunsmith Francis C. Lebeda.
