Awesome Art Deco Bench Polisher Rebuild - 100 Years Old!

I bought this antique bench polisher during the last hours of an estate sale. I didn't want to leave it there and have it be scrapped and since the sale was 75% off I got it for $15. The motor is from 1915 but other parts are possibly 1930's or so. It's incredibly dirty, needs electrical work and who knows what else. Can we get it back to work? Let's get busy!
