Good luck with the machine. It should be fun having your grandmother's machine and making it 'sing' again. Write up the story of it to keep with the machine, along with pictures if you can. That will give your machine a 'voice'. And these old machines do talk to us. They even know if they want to be named and what name they want to have. Or at least mine have told me theirs. I'm happy for you in getting the chance to get your grandmother's machine. That's wonderful!
