I believe that the oldest rescuee is my Davis made Minnesota Mdl B, Minerva. She dates from 1902 to 1909.
This was from a forum member who didn't want the machine, and neither did her friend who had it. There was a comment made that if nobody wanted it the machine would be tossed. I ... um couldn't let that happen, could I?
Then there is the Singer 66-4 Treadle #2. Allotment date is 9-23-24.
This one came from GW here in Springfield. Had been electrified some eons ago but the motor was gone. The old wiring was bad so I pulled that off and restored her back to a treadle. This machine is one of the best treadles I have.
There have been others, but I don't have pictures of all of them on Photobucket.
