Late to the party, but….
In case anyone is still interested, your machine is a later version of the Meister Klasse 101 sewing machine which was manufactured in Germany starting in 1948. There are several pictures of the Klasse 101 in the NeedleBar Picture Library Archive. The Meister Klasse 101s did not have the light built in behind the face plate, as yours does. The light was attached to the back. Meister also produced the same machine for an Australian department store. It was marketed under the name "Sewmaster" and was identical to the German machine with a few slight variations in decal placement.
These machines are dependable, heavy-duty domestic, all-metal workhorses with a high shank and 1 amp motors. They are comparable to the Japanese class 15 machines, with a forward-reverse mechanism and they sew both straight and zigzag stitches. The Klasse 101s often come with a tin accessory box that contains a zig-zag foot, a straight stitch presser foot and needle plate, a button attacher, a zipper foot, a quilting foot with guide, a rolled hem foot, a seam guide and what appears to be a felling foot. They take a #7 vintage Greist buttonhole attachment.
I own three of these machines, all circa 1952. I got the first one over 20 years ago and it is terrific. I am currently restoring the second one, and another (a white one) is on its way from eBay. Looks to be in rough shape but if it's anything like my others, is probably mechanically sound even if the paint needs to be restored.
These machines, although unusual, are not rare. I found two on eBay within the last three months. I have also seen a handful of listings on local Craigslists, Worthpoint and on the German eBay site within the last few years, so they surface from time to time. They are well worth the money if you stumble across one.
Hope this helps. The original post in this thread was very helpful to me when I went looking for info a couple of months ago and I hope someone can use what I found out.
