Thanks Caroline, one of the sites tells of what their serial number is, and for the life of me, I can't find one on my machine. I did find 3 numbers stamped under the base of the machine,( but figure that's the part number) and another group of 3 numbers on the hand wheel, (also probably part numbers) but don't think that's what they were talking about. Any idea of where they are, and what size needle it takes. I also need a new rubber for the winder as it had been left next to the handwheel and is flat on one side. Does anyone else have one of these machines? I'd kind of like to know just how old this machine might be.
