This is an older machine I bought it with the embroidery business and it worked fine. My friend used it all the time and she quit me and went back to the Waffle House management, it made me nervous to use it so I bought 2 single head Brother 6 threads (also for sale) . This machine needs to be serviced if for use. I think you could use it for parts if you have an old one . It has four heads and six threads per head.
