Yep I love mine. My case is in sad shape but the machine is as cute as can be and is quite the trooper for smaller work. One of my kids will be using this one primarily to sew when we get to that lesson

It's definitely a J, stamped right where you said it should be. I'm so thrilled. Going to see how she purrs right now. Dh is setting it up for me.

Now she purrs like a kitten. Had to clean out the bobbin area. Looked like they were sewing with red wool. It was imbedded in the bobbin area. Got it out after an hour of patience. Had to adjust the bobbin tension and now she works just fine.

Just a note that Singer used something that looked like red wool for oil wicks that are supposed to be there :) May not be an issue here but just thought I'd mention it.

Oh no...would the red wool oil wick be tucked in a spring in the bobbin area?

Yep. Hopefully these links will work for pictures of how to replace it and what it looks like in the end (tucked inside of the spring.)

Thank you sew much. I appreciate your response. Guess I did a bad thing. Actually, my bobbin case is squeaky clean. I can't believe the condition of my machine in comparison to the photos of the link above. The red felt wick was not long, evidently worn. I will replace it and oil it up well. Actually, the attachment case has a small tube of oil. I'm assuming it too is original. I'm loving my little baby more and more. I also have another old Singer that we picked up at a car flea market for $10. I still haven't tried that one. After the holidays, I will pay more attention to these machines and give them a good spa treatment. Thanks again.
