Missing Plate
Try Sew-Classic.com and ask Jenny if she has a plate that would fit your machine. I just got a Model 15 plate from her and it was very reasonable. Perhaps she either has one or can direct you to one. They are two to 3 times more on Ebay. Her bobbin cases are the most reasonable I have found also. I just got one for the 15 and it was $5. or so.
