Thanks, I will take the machine out and start on the case. This looks like a really nice machine. It's an old Montgomery Ward jewel 21 zig-zag. I assume it's an advance on the singer 15, as the bobbin looks like a 15 bobbin. It's turquoise and the finish is pristine. It has the cams, manual and some extra feet.
It looks like I'm not going to get to retire until the summer, so I have plenty of time to try different methods.
