Heavy Duty Electric Sewing Machine Home Mark DeLuxe Precision Model Serial number F(contact info removed) Our sewing machine repair consultant worked for Singer for YEARS. He verified that this is a heavy duty / industrial grade machine, good for sewing denim, thin leather, etc for personal projects or as a cottage industry (not in industrial amounts). In the sewing world, this machine is called a "clone" of the Singer 15 machine. At the end of WWII the US government gave the Japanese the blueprints to the Singer 15 sewing machine to help rebuild Japan's economy (and Singer was no longer making them). And the benefit is that these clones have upgrades from the original Singer machines - they run smoother and have extra features like reverse stitch and an easy switch to raise and lower the feed dogs, as well as the chrome hand wheel instead of the painted ones that seem to get chipped. They are work-horses, and often quite beautiful like this one! *You're sure to love her* A beautiful sewing machine in shiny turquoise blue with silver chrome details A lovely machine, all original In great condition, as seen in the photos Completely serviced and ready for you Straight stitch, with adjustments for pressure and tension Full steel body Adjustable stitch lengths Reverse stitch Bobbin winder with new rubber ring installed Generous harp area (work area between needle and right side) Strong 1 amp motor Work light Foot pedal controller The wiring is in great condition The bobbin winder is working well - you push it down onto the handwheel to wind the bobbin, and then manually lift it off when finished. :)
