WHY restore something that nice?
There aren't very many nice ORIGINAL machines out there. When they look that good, they should be left alone (in my humble opinion). When they are all done up perfect, they almost look fake to me. Something 50-60 years old should have a couple character marks. Now, when you find a rusted/abused machine, sure...restore the heck out of it!
Just my cent-and-a-half...
