That bamboo pattern bag is really cool, never seen that before.
My grandma used to have one of these that was a dark orange/reddish color, 3 speed (I guess 80s maybe?) Her sister gave it to her, and she used to use it to vaccum the kitchen and dining room after dinner. When I visited my grandparents I would use it. I always like the 3 speeds and the smell it made when it warmed up.
My other grandmother said she used to have one as well, but I never saw it.
Oddly, they said both of theirs burned out. The other grandmother said hers' caught on fire one day and she threw it out in the yard.
I never figured out why, because they weren't particularly hard on their vacuums at all. I'm guessing if you didn't keep the fan chamber clean it could cause these to overheat. Possibly vacuuming the inside of the bag too, because I noticed my grandma's was often quite linty inside the bag.
Interesting to see the motors in these, I didn't realize they used G.S. Electric motors, or I did know and forgot. Dirt Devil used the same manufacturer.
