Tony,
I have a model 100.6080-1 Kenmore (Regina) 3-speed twin head Floor Conditioner in the same color combo as your Magicord in the photo. The serial number is 605, which I think means May 1966. The speeds are as follows: 1 - HIGH for polishing, buffing, & sanding; 2 - MEDIUM for rug shampooing; 3 - LOW for liquid waxing & scrubbing. Except for the bottom plate's peeling paint & some resulting rust, it's in good shape and runs fine. Let me know if you'd be interested in it.
