LOL I can not tell you haw many times I have had one of those that far apart to replace the bushings and brushes that have worn through the years. Luckily I still have some new motors from that era still in the boxes somewhere in my garage in all of the parts I have in there. But I need to send a box full to be rebuilt so I have plenty for the next machine that might come through needing one.
Can you tell I am ready to go back to work refurbishing sewing machines! :D
