Really beautiful set, congrats on the rare find. No visible effects of damp or humidity on the aluminum panels, lid, etc. is telling of an easy life and a dry laundry room. Norge/MW machines were hit and miss, either they ran forever or were gone in less than 10.
Norge did make a robust and effective washer that sounded like a hay baler when running. I had one in the garage for a while and in the summer with the door open, saw a couple of startled dog-walkers when the brake solenoid snapped. We live in a smallish valley, so the sound would echo around the neighborhood, sharing that Norgey goodness.
I had a '68 MW set, found behind Lowes, and used it for a short while in the basement. The washer started spewing oil into the water and the dryer was, as Tom so aptly described, slowly "flocking" the whole room like a Christmas tree, so I returned them to the scrap pile.
