My Featherweight is an Anniversary edition, which I got from my Mom. She got it new back in the late 1940's. Still works like a charm. Regarding the "red" machines...this is a refurbished machine. Singer never made a red one according to Singer. You can read about read machines in the Featherweight 221 book...can't think of the author off hand, but the myth of the red machine appears in edition 2. The green was made, but it is a very light green, almost a mint color. You can always call Singer's toll free # and give them the serial number of the machine. They will be able to tell you it's "birth" date (mfg. date), color when manufactured, etc.
