I've been working on a similar machine. Here is a link to mine.
http://www.quiltingboard.com/picture...c-t162425.html others have helped along the way. The repair manual will be the same manual. I'm sure someone will post a user manual - otherwise the one for the 319 may be of some help - yours doesn't have the keys on the top. Sew-classic will have the parts you need and the special needles that machine needs. If you use regular needles they will tear up the bobbin case or shuttle.
