This is actually RB-25D USAAF s/n 43-3374 marked as B-25B 40-2344, the B-25 flown by Jimmy Doolittle during the April 1942 raid over Japan. 43-3374 was TOC 31 October 1943 and was retired in December 1957. It was then transferred to the North American Aviation plant in Inglewood, CA. There it was reconfigured to resemble Doolittle's B-25B. That was finished in April 1958 and the a/c flown to the USAF Museum. This slide was taken in the outdoor display area at the old museum. It is currently on display at the current museum in the World War Two Gallery.

This is B-25J 44-29035 marked as Col. James Doolittle's B-25B. On display outside the museum atrium on April 18, 2017, the 75th anniversary of the Doolittle raid on Japan. This a/c was acquired by the museum in 1998, and for many years was marked as a PBJ-1. It is now on display inside the main museum building in the WW2 gallery.

Ex N9753Z. It is now part of the Pearl Harbor Aviation Museum on nearby Ford Island. Repainted as a different Doolittle Raider (serial 02261) and part of an aircraft carrier diorama.

This Mitchell is in fact 43-3374, a RB-25D that has been restored to represent General Doolittle's B-25B and is on display in this diorama at the National Museum of the USAF.
