Seen here is one of the most successful and copied sewing machine designs in history. A descendant of the Singer 115 (see my other videos on that model), this machine popularized the Class 15 bobbin which is still in use today. This machine was so admired that almost every post war Japanese sewing machine maker created a version of it. Even Pfaff had a version made for them that utilized this design. With its oscillating shuttle hook and left facing tension dial, this machine was often referred by its fans as "The Farmer's Machine" due to its rugged capability to sew heavy material. Also loved by sewers for its use in free motion embroidery and darning as well. Most American versions were outfitted with direct gear drive or "Potted Motors" and are some of the strongest sewing machines ever made for home use!!
