Lara,
I got the parts for my 500 from my LSMG. He's got an attic full of machines, some of them donor machines.
My machine did not come with the face plate. If your dial up loaded my other thread you'll see the parts I had to replace to put it back in operation. Mostly peripheral parts, nothing but one screw internal. They can be had, but what the cost would be or where to suggest you start looking other than the LSMG is only a guess.
Sue,
The before pics of my last two 66s show them to look a lot like the one Lara posted the link to. That crinkle paint grabs and holds dust like you wouldn't believe. However it cleans up fairly easy. All I used to clean them is cotton balls, machine oil and in some places a tooth brush.
Love those machines.
Joe
