Not sure how to put thread on it or anything.
My first thing is to get a belt replacement and learn more about the machine.
I do belong to a yahoo group for treadle and old sewing machines, but haven't paid too much attention to it lately. guess it would be a good source of info and perhaps supplies.
I'm hoping the manual I ordered will offer some how to info on this baby. She doesn't have a name yet...I'm still thinking about it.
