Man, that s a lot of machines!
I see a few Orecks. Even an Oreck canister. Those would have tempted me, just because. Of course, as I sit here writing this, I have three fairly recent Oreck upright acquisitions at arm's reach. But, I doubt that I need to explain the sickness to anyone here. LOL.
In picture 11, I think I see an (at least slightly) older Eureka upright, maybe missing its outer bag.
And, I might spy a little Panasonic canister, similar to the one that I recently messed up while trying to clean it up.
Were these all available? I'm sure I would have taken some home with me.
