My name is Jackie. I was lucky to find thi Thompson pw 103-A mini walking foot machine. I have been searching for a user manual with no luck. I happened to see your post on leatherworker.net . Have you got any info on this machine? Do you still use it? Its so hard to find anything out. It's a mystery to me! I have it sewing like a dream and i love it but would love to know more about it. Hope this reaches you.
