Monogram released a 1/24 Cord model 812 years ago. It has been periodicall rereleased but the last time that happened was almost 10 years ago. You could try swap meets or e-bay to find one of these kits. As for the Lockheed Electra model 10-E there is a vacuum formed and an injection molded model of the model 10 in 1/72nd scale. Williams Bros. made a model of the 10-E in 1/53rd scale a few years ago and these kits are still available, again at swap meets or e-bay. Williams Bros. has gone out of business.
A 1937 Cord and a Lockheed Electra model 10-E equates to Amelia Earhart. The Cord was pale yellow with tan leather interior. The original purchase order is in the special collections at Purdue University in W. Lafeyette Indiana. There is also an old newspaper article describing the car. The Cord-Auborn - Deusenberg museum in Indiana should be able to identify the exact color of the yellow used on that model year, as well as the color of the leather interior.
The Electra was mostly natural metal except for portions of the wings that were painted international orange (Testors Model Masters paint). The same orange was used on the horizontal stabilizer. The leading edges of the wings were painted black. The aircraft did not have deicer boots as some have suggested. The black area was paint. The Williams Brothers kit has the areas painted correctly identified but the decals provided for this purpose are the wrong color. The decals provided are almost red. Of note is that the aircraft was also purchased by Purdue. Viewing the special collections is by appointment only. Good luck in your quest.
