And, I might note, the above listings are just the ones found in the "vintage vacuum" department. There are other vintage sweepers all over the place on eBay, mis-categorized one way or another or their names misspelled.
Surely someone should comb through the eBay listings for these mis-filed machines in =particular= ... lest someone overlook them and miss their chance to bid on them!
(Hint: There's a **very** rare Electrolux Model 20 tucked away in the wrong section. I'd tell you all where it is, but I know that if I do, at least one person would be furious with me!)
