As rusty as that looks, I'm thinking that Evaporust may leave the metal black (or at least that has been my experience). Some have better luck at polishing it back to shiny. Brasso or other metal polish with 0000 steel wool might work with some light rust. I also have heard that citric acid is a rust remover. I did get some but haven't used it for rust removal, yet. Do you have a dishwasher that uses powdered detergent? I think there is citric acid in that. I have also used Oxy-clean (generic) to simply clean attachments before I polish them. Just make sure they get dried well.

Be careful with PB Blaster so you don't get it on the paint or decals. Liquid Wrench (old fashioned) or kerosene or lamp oil may work as well.

Sorry about the shuttle bobbin. Maybe JoeJr can help some light on that or maybe someone else.

Step 1, lots of "before" pictures
Step 2, lots of sewing machine oil

Thank you for the warning about PB blaster on the paint. Ok, only for exposed metal, I think I will wash it gently first to see what may really be rusty as compared to dusty. The movement is so smooth! A missing shuttle bobbin just makes things more exciting.

Is the kerosene or lamp oil or liquid wrench for the possible rust instead of using PB blaster?

Yes, and then lots more pictures preferably, some posted here.

Those are mostly for loosening up parts that are gummed up with old oil. Sounds like not needed for your machine - since it is working smoothly.

Thank you. I still have a house full of company. I promise to post the good shots if I ever get to take the things, and if there is something you want to see that I haven't posted, don't hesitate to ask for a specific picture. You may see something that I don't so the more eyes the better.
