Thank you - I know there are some Singer 66s, 99s, Spartans, 185s - I forget what the 201 is like and there are others that need to be cleaned!!! I don't need to see any more machines at the thrift store just because nobody cleaned them out! The Singer 401, 403, 404, 500 and 503 all clean just about like that too. With them there is no positioning finger. There is a holder on a spring next to the bobbin holder. It gets pulled up and to the right, the bobbin case comes right out. Re-assembly - see owners manual. It is a little tricky the first time but not very hard to do if you persist. I managed it with no manual.
