Carl Scholl passed along some photos of the B-25 Aero Trader put together for the Pacific Air Museum. That museum, which opened its doors in December, displays what appears to be Doolittle Raider B-25B s/n 40-2261. Typically, Aero Trader did an incredible job on the airframe, which is actually a composite of three B-25Js: s/n 44-30077 (cockpit and tail), 44-30627 (wings), and the center section from the static B-25 used in the crash scene in
Forever Young which I think is s/n 44-30090 (not sure about that).
Notice the attention to detail in the tail gun area, the cowlings (collector ring vs. ejectors as on the B-25J, turret placement, and changed fuselage windows to bring it to a "B" configuration.
The museum got this Aero Trader effort in part for the exchange of the corroded B-25J 44-31504, the remains of which are sitting on the Aero Trader ramp at Chino but about to be moved down to their storage yard in the desert near Ocotillo Wells.
