Arnswine, you forgot two important companies; The American Bantam Car Company, and Kaiser. American Bantam of Butler, PA, designed and built the first US Army Jeep. Willys, and Ford Motor Company had the manufacturing capacity, so they were awarded the contracts to build most of them for WWII. Willys started production of the Civilian Jeep (CJ) ASAP after the war ended.

In 1963 Kaiser bought the Willys firm, and kept making the prime product, The Jeep. The Kaiser organization sold the firm in 1971 to Roy D. Chapin, Jr., the CEO of American Motors.
