This may be a repeat on other topic page, but when I was in high school my Mother's Featherweight need to have the bobbin case repaired. At that time the singer company would leave a machine for your use while your machine was being repaired. The rep left a Singer Slant-O-Matic 401A and I would come home from school every day and sew on it. When Featherweight returned I came home to see the two machines sitting there in our dining room. My mother and father purchased the 401A for me! It was my Christmas present, Birthday present and Graduation from High School present. It has been with me all these years through every sewing task asked of it. My daughter has the Freatherweight now.
