Thank you, Paul!
Your ability to dig up information always amazes me.
Right off the bat, the rear wheels on both of mine appear to be the same.
It's a little difficult to read, especially on the dark brown of the 2201, but I believe the power ratings are the same on both.
I'll attach a picture of the inside of my 2210. It always struck me as odd that the panel in front of the cord winder is orange. I figured it had been replaced at some point. But, it may have been John who told me it may very well have come from the factory like that. If Hoover had some extra orange parts laying around, they would put them to use.
Also kind of strange, that panel in general is not present on my 2201. It doesn't really look like it's missing. It just looks like it was never there.
