If they really made 10,000 of them, someone other than the Kirby company would have one. When you make 10,000 of something, that means you have to sell 10,000 of something. The machine would've had to have been supported by the company in someway by parts. Other than the one sheet of printed sales material I've seen, that cleaner was never mentioned by anyone in the vacuum cleaner business. In the 1930s, many companies were refurbishing vacuum cleaners for sale either through dealers, or directly to the public. I have dozens and dozens of those catalogs, mentioning every known vacuum cleaner except This one. Which leads me to believe they were never sold.
