There's a little (2-1/2 inch) squirrel cage blower on top of the machine. The pile of mung you see there came out of the blower housing. Barely room for the impeller to turn. 100 years of baked on oil/butter/whatever, paint thinner and even carb cleaner wouldn't touch it. Had to set it afire with a propane torch to soften it so I could scrape it out.
Ordered sufficient period correct braided cloth-covered wire in various colors to completely rewire it. Blower motor, kettle motor, 4 hot plates, kettle heater and lights. As long as the hot plates and kettle element are good, it shouldn't be technically difficult to get it back in service.
