Data Bleg on Post-WWII Transition

You can get a good overview at the Ford Motor History site, which breaks down the companies history by facility (read down the left-side menu for a general timeline with links to more detailed history.)

Fun side note: See this article discussing Ford's Willow Run factory, where the company manufactured B-24 Liberator bombers during WWII. Its layout was rather strongly "influenced" by county-level tax avoidance considerations.

You might try contacting Alan Greenspan for help. I seem to remember him writing about being on top of that kind of statistical data when it was happening.

I found a paragraph about WWII production at Ford Motor Company that was interesting, in An Empire of Wealth: The Epic History of American Economic Power, by John Steele Gordon. It's on page 354.

Also, Illustrated History of Ford by George H. Dammann, has four pages of illustrated wartime production.

On a similar topic, there is a lot of data and a lot written about Oak Ridge, TN, otherwise know as Atomic City during WWII. It went from a population of a few thousand in 1942 to almost 100,000 by 1945 to develop the uranium and the atomic bombs for the Manhattan Project to end WWII. Within a couple of years after WWII, Oak Ridge reverted to civilian control and enterprises.
