I was just reading the thread about what damage GOOP can do to a machine's decals...glad I read that before I did anything more to this one. It really isn't that dirty, but the decals are faded. Chances are, someone along the line gave it a good cleaning and wiped them away...hmmmm.
I also bought a Singer at the estate sale. A Singer Stylist 457. I've been cleaning it up, it was a bit musty
but it's getting better...but it has a squeak. I haven't tried sewing yet, I wanted to oil anything that was metal against metal before I did too much. The plastic gears all look good, but I just can't determine where the squeak is coming from. It doesn't happen when I disengage the motor to run the bobbin winder. It seems to be getting a bit better as the oil gets into the joints, so I will see what it does when I thread it and try to sew tomorrow.
