Oops. You are correct. I have the class 66 bobbins since both Mabel and Ernestine use them. My brother takes the class 15. I must have not had enough coffee this morning when I answered. I did read that the newer plastic bobbins don't work well in the older machines, so I purchased some [class 66] metal ones. I have enough now since three came with Ernestine when I purchased her.
