Nice thing about older mechanical machines, they can all get running again for the most part.
I have 2 FWs...one from 1938 that is in pristine condition except for the case, and needed a new bobbin winder when I got it (the wire was missing to hold the bobbin...not much of an issue, the part is the same on all of them). This is the machine I use when brides add on my delivery, dressing and repair service for their weddings...I take it just in case something happens to the dresses. The other is from 1953 and needed work. It took me about 6 hours to get it running and un-froze and cleaned, now I need to a new plug myself to make it run.
