I already contacted him about two weeks ago and heard nothing back. I went through his site but he didn't have a lot of information about the German specific. I know that they are quite scarce, at least in the country, but I was looking more for the history of the copper plate. Interestingly enough in a unit where everything was scattered about this was only one of three that was wrapped and carefully protected. The other was the 101 and the last was a 201 bicentennial, which is perfect.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.
