Thank you for the response and advice, Mickey2. The machine decals and finish are in surprisingly great condition. It looks like it sat in a covered shed or garage for years and years. Lots of dirt, and cobwebs, and tons of old lint and dust inside and underneath. It didn't have a cord, but I was able to test it with my mother's 201-2 cord. Of course, it worked and sewed perfectly.
It sounds like persistence, patience, and lots of sewing machine oil will make this jewel shine and purr along again soon! She all ready looks 100% better than she did. I replaced the spool pin, bobbin tire, and I ordered a new cord and controller.
