Hamilton Beach Drink Master #30

Just found this Hamilton Beach Drink Master #30 milkshake mixer at an estate sale.
The condition is about the nicest I've ever seen, in fact I thought it might be a repro at first glance.
The price was only $10 and it works perfectly. It also comes with the original heavy plastic cup, which I have never seen before. The stainless steel cups are easily available and it might look better with one rather than the plastic.
