Shortly after the end of WWII, the Eaton Manufacturing Company, published A Chronicle Of The Aviation Industry In America 1903 1947, subtitled "A Salute To The Aviation Industry." It went to press in November, 1947, and was copyrighted 1948. It consisted of a detailed timeline of aviation developments in the United States up to the date of publication, which, of course, included the entire War. The copy in my posession was originally distributed to members by the Institute of the Aeronautical Sciences.
Eaton was (and still is, for that matter) a highly diversified company. Their ads for the war period, as shown on their website, feature automotive driveline components and part for aviation engines. I have not found ads under the Eaton banner in my magazine collection. If there were any from subsidiaries, I have not been able to identify them.
For now, I will index by year. Later, I may spend the time to expand the indexing, but for now it is not high on the priority list.
