Those of you that have some of the newer Singer Featherweights and others, can get a certificate from Singer with your name, the serial number of your machine and the year it was made by going to mysingerstory.com and putting in the info requested. It is a neat certificate that you can then print off.
I wasn't aware that the 221's were made after 1964. That is the date most sites on the net have as the last they were made. Is that just in the US? Does any one know why this is? Also there were some made in the 1940's that aren't listed under the 221's groups in the serial numbers. Why? I know, I'm filled with questions......
