That's a beauty. I learned to sew on my mom's 15-91, which I now have. My first foray into sewing was making doll clothes. So, looking at yours makes me nostalgic.Mine is not in the same great condition as yours, though. It spent years in storage, so the wiring is compromised and the finish is dull. I still love it though.
Congrats on a beautiful machine.
