Sorry, no help but I just had to reply. I opened this thread thinking it was going to be a wish thread -- if you could have a wizard inside your machine, what would s/he do? But then I saw your pic -- gorgeous machine, by the way -- and thought "sewing machine, candy necklaces & a nearly empty bottle of rum: this lady is my kind of quilter!"
Hope someone else knows something about your machine. You might also try asking in the Vintage Machines forum. There seem to be people who know something about just about every kind of machine ever made there.
