I was digging around for some spool pins which I never found but I did find the missing screw piece for my machine. I'm thrilled to pieces to know what it should look like Manalto!!! Thank you. Now I'll have to bring that machine out and get it working.
I think there were some designs at that same time to do monograms with varying widths - there should be examples in other manuals from the day. I vaguely remember seeing some in an Elna manual I had back in the 70s.
