I just bought Featherweight #4 last week at an antique mall type store,its in fair condition. I cleaned and oiled it, this poor machine had more lint in it than I've seen in years of doing this for customers; it even had it around the inside of the hand wheel. I'm happy to report that after her spa treatment, she sews a beautiful stitch. "born" in 1950.
The paint is gone on the front edge as are the decals,so this tells me that she has sewn miles of fabric.
