Exactly! Don't store machines with thread on the bobbin. (Or fabric under the foot!)

Well I learned something new there!

I will give it a good soak with the sewing machine oil and let it set for a few days. I was just wanting it to work now! I will try to get a picture. It doesn't look bad at all from the outside of the bobbin case. In fact, it looks great! Just won't come dislodged. I have taken off the needle plate and took some fuzz out of there and then cleaned it real good.

That maybe why you were able to buy it.
Don't yank on it - the little latch on the BC might fall off. Do what everybody already says - oil it and then when it has had time to soak try to rock it back and forth - juggle it and see if it comes off. I've seen them rusted up like that too but they do clean up and run eventually. It could have thread or lint stuck in there somewhere, too. The oil should help with that.

I always store my machines with a fabric square under the foot. I've been taught over the years to avoid metal to metal contact on various machines.

That said, I've bought many machines with fabric under the feet and not one had rust because of that.

However I have had many with rusted bobbins under the thread. So I don't usually leave a threaded up bobbin in the machines.

I suspect if the machines were stored for years and years with fabric under the foot I might see some rust, but so far it's not been a problem.

The amount of humidity where the machine is stored may be a factor.

If any of those machines have been in or around coastal areas the salt air can do a nasty rust number on them.

we were taught to always keep a square of facric under pressure foot when not using back early 50s

I’ve heard that before too, and have often wondered where it originated....especially while I was cleaning rust off of a feed dog.....

Salt air has played havoc with a Singer 328 I have. It came from Florida. Lots of poc marks of corrosion on the top and under the hand wheel.
Minimal rust elsewhere. Once I get back round-to-it I'll sand it down and repaint the corroded parts.

I recently picked up a Kenmore 158-?????? that had a badly rusted bobbin case. It had no bobbin in it. No rust on the feed dogs or other parts. No where as bad as the machine CD posted the pic of.

I ended up parting out the bobbin case and putting in a new one. It was so pitted the thread wouldn't pass between the tension spring and case body without fraying.

I've often wondered if the bobbin case rust wasn't due to corrosive body chemistry as much as the thread in the bobbin absorbing moisture.

I do know lots of machines I've refurbed have had the most touched places, bobbin cases, presser foot lever, stitch length lever rusted and pitted. That's just a theory but it works on paper.

As for the cloth pad under the foot, I started doing that when I replaced a half dozen feet that were severely worn from running and resting on the feed dogs.
A lot of the newer aftermarket presser feet are made of aluminum. Contact with the steel feed dogs will cause wear.
So the cloth pads will prevent that.
