A couple of nice prototype machine firm images I discovered:

Quoting Smithsonian National Air and Space Museum | Vought F4U-1D Corsair:
By V-J Day, September two, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design and style allowed ground clearance for the enormous, 3-bladed Hamilton Normal Hydromatic propeller, which spanned more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the biggest and 1 of the most effective engine-propeller combinations ever flown on a fighter aircraft.
Charles Lindbergh flew bombing missions in a Corsair with Marine Air Group 31 against Japanese strongholds in the Pacific in 1944. This airplane is painted in the colors and markings of the Corsair Sun Setter, a Marine close-support fighter assigned to the USS Essex in July 1944.
