It's a 6370 or thereabouts. I found it on Google images. It's bad to freeze up. It also has a camstack that is prone to cracking. I found a youtube video where the guy shows where to look for the cracked camstack and another piece that I don't remember right now.
I'm beginning to think that I may have about 10 parts machines of assorted brands. I may have to learn about parting out sewing machines. Wonder if there is a youtube video on that?
