Questions surrounding a baseball autographed by Dizzy Dean, a brass eyeglass containing an image of Jefferson Davis, and a question on credit for an oil-drilling device. Included: investigation of a 1944 baseball game in which the players supposedly included Dean, Satchel Paige and an Air Force staff sergeant; whether an eyeglass belonged to a Confederate supporter; whether a twin-cone roller-rock bit was invented by Howard Hughes or a San Jose resident's grandfather.
