To all who posted these,
Fantastic!
What I had was far more modern.
The tank that Dave posted in reply 42 is close to what my Electrolux XX (20) looks like but mine is on runners. As for the box in reply 43, this is a lot like the box that was in the storeroom at Choate School, back in 1953, but it would have held a model XXX. As for the "crazy wands" in one of the first pictures of the Electrolux V, or X1, the curved wands were original to the V in 1924. As for the strange cord plug (machine end) that's the way the models X1 and X11 looked. Since Electrolux did start in Sweden in the early 1920's (maybe before) they were sold in Germany, Hungary and I think Poland, so a few must have gotten to Russia, or else the V, X1, X11, and XX were copied years later. Certainly the Fair Fax was.
This is a fascinating thread, and lets me see a few of the things that are out there.
Thanks for sharing.
