I used to have an old 1920 Elna sewing machine with cams. I sure made alot of clothing for my children as they grew through the yrs. I traded it in on a new Elna in 1992. I just love it but wish I could trade it in for one with longer head for machine quilting. And I wish I still had my old Elna too. Must be a collectors item now. Silly me. Hope you find a piece to replace the back on it.
