I got the machine mostly reassembled now, seems to run good. It has 6 inch wheels on it, the perspective in the photos makes them look bigger than they do IRL. I've just got to get the cover / KO seals on the j box and find some new oil wicks for the oil reservoirs on the motor; the old ones were rock hard and were sitting in half an inch of old jellied oil. Eww. I originally got the machine because you can grind on the flat side of the blue wheel instead of the edge. That side-of-the-wheel style of grinder is real hard to find for some reason, IDK why, there are a lot of times a flat grinding surface works better than the curved edge of a wheel. I do really love the old time styling of this machine.
