Billy (Lostn51) may have parts. You can post in the vintage sewing shop - just reply and post your picture and questions or cut and paste this thread. There are 750+ pages, but it's an active thread. There are others there with some parts available, too.

BTW, you new 'Old Gal' is very nice. I have a 128, but I'd like a full size one.
