Let me try to find it on the Internet. It’s the one my beloved Mom gave to me on my 18th birthday. Got it out of the shop yesterday where the man completely oiled it and made sure it’s in prefect working order. He said it’s now a rare one and was one of the best Singer’s ever made! Portable and I saved all the attachments and the instruction book. It needed a new belt of course, after all these years (decades). I’ll send you the link.
Wow ... sounds like a treasure .. and may be a Featherweight, which quilters crave for their perfect straight stitching. They have model #s ... i.e., 201s, 221s in great condition are VERY sought after and valuable.
