Chigger Holler Quilter, I think you have your Featherweights mixed up. The older machine should have the fancy scrollwork face plate and the striated plate started appearing on Featherweights after 1950. Sometimes face plates are changed but it's not a regular thing. Face plates are one of the first clues as to the age of your Featherweight and older Featherweights do not have 221 on them. Happy stitching.
