I have been searching for contracts, documents, etc for the use of the plane by MGM but no luck so far....I wonder if any of those scale models would still be around? ..Humm with( Nacelle's painted same color as the Electra)...looked on several antique sites ( including ebay), but no success thus far, wonder if MGM can help?
If Mantz attempted to keep the Electra's use a secret from Earhart/Elliott, It doesn't appear like he attempted to remove the paint job it received for the movie, as it seems it was still in place when Earhart inspected it prior to the Bendix race.
