Thank you Janey for the resources! The old singer sewing machine blog is great!
JoeJr - This does have sentimental value and I would love to be able to use it. I have a modern sewing machine but I learned on a very old singer and would love to keep this if I can get it working. Thank you for the advice that this might not be the best project for a beginner! I think I will talk to the service person for the actual maintenance and then I can attempt the cosmetic stuff after it is working.
