After reading all the stories about Featherwights etc., I decided to get mom's old machine out and see what it was. It is a Singer 301, has all parts and the manual. I know it was purchased in 1953 or 1954. According to the internet it is the big sister of a Featherweight. It weighs 15 lbs. vs 11 lbs. for a featherwight. My husband cleaned and oiled it and it worked beautifully.
