Well, I have worked on hundreds of these machines, and have never seen a Featherweight 221 with the serial number anywhere but on the underside. There are other Singer models that had the serial number on the top right under the badge. Remember Singer made lots of different models and had other two letter, number, number, etc serial number. I don't repair those other models, just 221s. Send a picture for more help.
