<-------That is me because after hunting for many, many months I found my treadle! It's a 1916 Singer 66-1.
When I answered the CL ad, it turned out to be the dental hygienist I've been seeing for the last 20+ years. It had been her beloved great aunt's and had been on display since the aunt died in 1985. As you can imagine it was a bit difficult for her to let it go but she was happy to see it go to someone she knew and that it would be put back to use. I also have a few stories about the aunt who was a character!
I'm still in the process of cleaning her up. The bobbin winder had been removed because it wasn't working. I was able to clean it and it is now working. Unfortunately they lost the screw that holds the winder to the machine. I've been trying to find a replacement with no luck. Does anyone know where I could find one?
