When i found the way way overpriced Singer Sunday at the antique/consignment mall, they also had another machine.. the cabinet is in pretty bad shape. When I opened it up, it had an Adler machine, kind of a seafoam green color with an eagle and "Made in West Germany" on the front of it . I couldn't find a serial number, but the manual was for a model 189a. It had a few attachements, and uses cams for decorative stitches. I looked on the web but haven't found much about it. They didn't have it priced, so just curious if anyone knew anything about these machines.
