Features: This is an old model, dating back to around 1975 (Showa 50), but it's known for its simple construction and high durability. While it's heavy, it's also a powerful machine. It can sew everything from thin materials to thick ones like leather, and it has the strength to sew through 7-8 layers of denim without a problem. It features a full rotary hook, a lever-type reverse stitch device (back tack), and an oil-lubrication system. Comes with the original motor. Includes instruction manual, bobbins, and bobbin case. Spare belt included. I've used this sewing machine for my side business, creating various works. It still has plenty of life left in it. I'm selling it because my creative process has changed, and I've purchased a new sewing machine. It's a straight-stitch-only machine, so it's less prone to breakdowns (I've never had a problem with it during my use).
