This expanded third edition of Nancy Johnson-Srebro's classic guide on the Singer Featherweight 221 sewing machine gives you even more to be proud about owning one of these lovely workhorses. New information has come to light in the years since Nancy's last edition. She put all this new information in a supplement at the back of the book so you can easily get updated, and the new information references the applicable page numbers in the rest of the book so you can look up the background information quickly. Also includes history, maintenance instructions and diagrams, and attachment information as in the former editions.
