When I first found this website I remember loving to read all about Hoover history, and the original Spangler model sounds like the absolute rarest. I know Hoover has (had?) one in North Canton, myvacsrock has one, and a former member posted in this thread of a non-Hoover label Spangler.

It looks like there's one in the National Museum of American History.

So are there only 4 known left to exist? I haven't read about it for years, but maybe I missed something. Any new "barn finds"?
