Wasn't the cockpit section on the flyer from the house in Pacific Palisades, CA where an individual bought two noses for a camper?
From 1990 to 1993 I was an almost every Saturday hang out kid at Chino, and I researched a lot of info and on this stuff for articles and my own files.
The cockpit section of the ex flyer 1464 is from one of the other Million Dollar airplanes, 1501. This was flown by Glenn Doolittle, who lived in San Diego county until his passing a few years ago. I called him about 20 years ago, he wasn't very sentimental about his WWII exploits, but he was a very friendly, nice guy. He told a funny story that bases would get word that "Doolittle" was coming, roll out the red carpet and out stepped Glenn, who was not related! The two noses came from Chino itself when it was a scrapping yard after the war. One of the noses was four serial numbers away from the crashed CAF aircraft Carolyn.
Oh and the one Saturday I decided not to go to Chino during those three years? April 18, 1992, the Marauder's first flight. That was devastating.
Made up for it a year later being the first to shoot it air to air, but still, missing the first flight in 50 years sucked!
