Authorized reproduction of the users / instruction manual for a Sears Kenmore model 37, a round bobbin, zig zag sewing machine. It has information and illustrations of the cam based stitches and making buttonholes. It also has basic information, cleaning and oiling and some troubleshooting information. There is an ink stain which is on at least half of the pages. It effects the upper corner of the pages. Very little information is covered but I want you to know that it is there.
