Thompson Mini-Walking Foot sewing machine, model PW 103-A-GPB. This is the machine that eventually became Sailrite. As a matter of fact, parts for this machine are still available at the Sailrite website. It's a portable industrial walking foot machine, designed to handle heavy fabrics such as sail canvas, marine and other upholstery, denims and leathers. Straight stitch only, with backstitch. Small enough to stow onboard for emergency repairs, and can be used without electrical power if necessary. It's in great condition, and ready to sew. Included is the original instruction manual, foot control and case.
