I don't know what this is, or what it's for. I have had it for years (20 +?) and never used it. I am thinking of a complete teardown and repaint, if I can come up with a use for it. I just broke it out of storage. I want to sew with it just for the fear rush. lol. The plate says 72 W 19. It lacks a motor, and needs a tuneup.
