I got this 1920 Minnesota A (Sears knockoff) from my SIL and I have been using Billy's tute to dismantle and clean it up. It appears to have been a treadle machine retrofitted with a motor, and not very nicely done either. My question is, what is the purpose of the long skinny bar that is attached to the motor and slants down to the bobbin winder. It moves freely between the attachments and as far as I can see, does nothing for the machine. Any ideas?
Second question, what do I do with it now? It is not in very good cosmetic shape but does sew and I do not want to keep it.
Thanks for any ideas.
What is this bar?
