You've got a great machine there, one of my favorites. I've had two -- the 6440 and the 6570. Do all the dials turn freely? After a certain age, they tend to freeze up and require maintenance from an experienced SMG. The other common problem is the take up lever which tends to break after a few decades too. Sometimes the camstack needs to be replaced also. However, once it's in tip-top shape, it's a dream to sew on, really sweet. You can get a list of trusted mechanics in the file section of the Yahoo group.
I see you have a few cams too. You're showing my very favorite, the B cam with that graceful serpentine stitch. Love that one!
Congratulations, and let us know how it turns out.
PS Let's see if I can upload a pic of my baby.
