Authorized reproduction of the users / instruction manual for a Sears Roebuck and Co., Simpsons-Sears-Limited, Waltons-Sears LTD, Lady Kenmore model 89 or model 516.891 a Gritzner GU Wondermatic (which is made by Gritzner-Kaiser and built in Germany) and may be a Pfaff model 280. It is a round bobbin, zig zag sewing machine. It has information on the built in buttonholer, its built in stitches, as well as illustrations of the stitches that it produces. It also has basic information, cleaning and oiling and some troubleshooting information. Bernie Pokorski who is a very knowledgeable sewing machine hobbyist and a good friend told me that this; The Lady Kenmore Model 89 (516.890) and the Pfaff Model 280 are the exact same machine, except for a few cosmetic differences. So, the Kenmore Model 89 is a very workable substitute manual for it.
