There is a man called Alex Askaroff with a site called sewalot.com in GB. He is a wizzard with machines and has written many books about England ans has sewing publications also. He would know about your German machine. They are a little on the rare/scarce side in the US. I have read about them online. Maybe ISMACS.com site would help. They have international info. also. Congradulations on your neat find. You will love Alex's books. Our library has some of them.
