I have one of those machines too. They are nice. Mine came minus the wiring so I had to get a slightly different motor for it to match the cord set I got from Sew-Classic. And I don't have a box. Mine came with the bottom that slides down into a box, rather than is the bottom of the box.
Do you think you could take a close up pic of your presser foot and do some measurements of it for me? I still haven't found an original foot. I've got a real good one, but it's not original. Knowing the actual measurements could help me find the right ones for my machine.
Where do you find the dates of manufacturer for these machines?
