Pick your poison: Main equivalency!

Howard Hughes commissioned Interstate Aircraft to make a vacuum for his TWA airliners during WWII. Interstate Aircraft was owned by a personal Friend of Howard Hughes, a man who co-designed Hughes pre-WWII racing airplanes. Howard Hughes specified the vacuum had to be small enough to fit under an airline seat and wanted it as light weight as possible, hence the use of the Magnalite magnesium-aluminum alloy in the vacuum body.

Compact Model 1s were already in production during WWII. I have an example of one that was made in El Segundo. They were made alongside the Kadet trainer, TDR unmanned bomber and other aircraft components Interstate Aircraft was building as part of the war effort. That plant in El Segundo was closed right at the end of WWII when aircraft production ceased. Interstate Aircraft sold their aircraft production tooling, changed their name to Interstate Engineering Company and moved from El Segundo to Anaheim. I have seen Compact C2s with data tags indicating they were made in El Segundo so that tells me that Interstate had already gone from the vertically split body used on the Model one to the horizontally split body used on the C-2 and all subsequent Compacts and Tristars since before the end of WWII.

If you still insist on claiming that your research is correct then kindly post that here. This is what my research has come-up with each time I google it. This is what I came up with from both "Google & Chatgpt" They both say the same thing. I've already posted that Howard Hughes commissions' Interstate to design a vacuum cleaner that design was the very first Compat design. Compact Model 1S vacuum cleaners were not in production during World War II, as the company that made them, Interstate Engineering Company (IEC), was focused on manufacturing for the war effort.

I wish I can find one some day. They are very elusive over here.

You have to scroll down a bit but this old LA Times article from July 1945, two months before the end of WWII shows Interstate Aircraft selling their aircraft manufacturing side to Harlow Aircraft to concentrate on making vending machines, small gasoline engines, refrigeration compressors and vacuum cleaners.

"Regarding the sale of the light plane division, Don P. Smith, president of that postwar plans for Interstate will require all available space formerly used fort the manufacture of the Cadet the manufacture of soft drink dispensing machines, refrigeration compressors, vacuum cleaners, a line of small gasoline engines. Paint Concern Orders Extra NEW YORK, July of Sherwin-Williams Co. today declared an extra dividend of 75 cents a share on the common stock in addition to the regular quarterly of 75 cents, both payable Aug. 15 to stock of record July 31."

Interstate may not have sold a vacuum to the public until 1946 but they were making them for TWA before the end of the war and the examples for TWA mostly likely used different motors designed for the three phase 400 Hz power found on aircraft.
