Loaned to Pima in 1975, where the marking of 'Sentimental Journey' were later applied. Some of the wartime stories include crew complaining about the lack of windows in the back. A flack hit fixed that problem for him. Battle damage repairs (on the flap) can also still be seen. The aircraft was part of a squadron where the aircraft were named after the 7 dwarves. This one was named 'Dopey'. another surviving B-29 is the famous 'Doc'. The aircraft was used in the filming of the movie Enola Gay.
