Hi Billy, I just acquired a Singer Red Eye (66 I guess) It's a treadle, Anyway I've been trying to clean it up my self and I have an extra spring that I don't know where it came from. I know that I can't left the presser foot now. I was cleaning the inside with a pipe cleaner and it did pretty good, got it almost done when I found the spring in the botton area where the presser shank is. Can you help me or do I have to take it in
