My Dad has a whole bunch of metal power tools from the 50s and 60s, although they're all Black & Decker. He's got 3 of the "classic" drill design, plus a skilsaw, heavy-duty drill, right-angle drill, and some other things that escape me at the moment. IIRC, the "classic" designs have a grounded plug; not sure if it actually came with one, or if it's a replacement. Pretty cool collection, and they all still work just fine.
