Here is a superb, original, 1936 Singer sewing machine model 15-91 with the super smooth running potted or direct drive motor. This machine sewed incredibly smoothly and sewed a perfect stitch top and bottom. It has the beautiful Art Deco scrolled face plate and side cover plate. This machine bears serial number JB 007250 The 15-91 is a beautiful sewing machine and is heavy duty able to sew fine fabrics and light leather and thick denim. This machine has been fully tested to sew a beautiful stitch as seen in my photos. The top stitch is pink and the bottom stitch is white. We tested all functions.
