First
Nice looking machine .it’s almost to clean to restore .But
I believe the machine is made of aluminum but check me on that as I’ve never owned one . The rest of the parts you’re talking about like the coin mech and other smalls a lot of people soak them in simple green . The outer doors were not polished that I can remember more like just a clean raw finish .I’ve seen them polished and Chromed .if you want that look .
Keep us up dated !
