Mint, LOL, yes, I was thrilled to be lucky enough to purchase this one. Persistence and patience paid off.
Robert, if the impeller is bakelite it sounds quite possible that it could be broken. I'll have to tear down the machine to find out. I'm assuming I'll have to turn the thing upside down and/or remove the rear panel to get at the "guts" of this thing.
One thing I'm going to do right off, is to put bigger wheels on it. My second kitchen has a real brick floor, without much wear, and it's pretty rough with the mortar lines and all. So the little 2 inch wheels have a hard time rolling around on it. I'll probably get 3 inch ones, with locks for the front.
Mr Clean, thanks for the date correction. 1951 did seem a bit too early, espeically since the original power cord has a three-prong grounded plug.
Well, time to get back to the job.
