A handful of nice china prototype company pictures I found:

Quoting Smithsonian National Air and Space Museum | Vought OS2U-three Kingfisher:
The Kingfisher was the U.S. Navy’s main ship-based, scout and observation aircraft throughout Globe War II. Revolutionary spot welding techniques gave it a smooth, non-buckling fuselage structure. Deflector plate flaps that hung from the wing’s trailing edge and spoiler-augmented ailerons functioned like added flaps to let slower landing speeds. Most OS2Us operated in the Pacific, exactly where they rescued numerous downed airmen, including Planet War I ace Eddie Rickenbacker and the crew of his B-17 Flying Fortress.
In March 1942, this airplane was assigned to the battleship USS Indiana. It later underwent a six-month overhaul in California, returned to Pearl Harbor, and rejoined the Indiana in March 1944. Lt. j.g. Rollin M. Batten Jr. was awarded the Navy Cross for producing a daring rescue in this airplane below heavy enemy fire on July 4, 1944.
Transferred from the United States Navy.

Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress "Enola Gay":
Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of Planet War II and the very first bomber to house its crew in pressurized compartments. Even though developed to fight in the European theater, the B-29 identified its niche on the other side of the globe. In the Pacific, B-29s delivered a selection of aerial weapons: traditional bombs, incendiary bombs, mines, and two nuclear weapons.
On August 6, 1945, this Martin-constructed B-29-45-MO dropped the initial atomic weapon utilised in combat on Hiroshima, Japan. 3 days later, Bockscar (on display at the U.S. Air Force Museum near Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Great Artiste, flew as an observation aircraft on both missions.
