Mechanical stuff and plastic woes!

 I was sent a mechanical Santa and Mrs. Claus to see if I could restore them. They look to be from the 1980's. They both sit at a piano which stayed with their owner. I just got a plastic bin into which the Claus couple had been unceremoniously stuffed.

First out of the bin is Santa Claus. He isn't too bad. His feather quill has broken and he has a few spots to clean.... but he works!
