I actually found this keyboard one or two months ago in my basement, but only got around to cleaning it recently. It is Made in West Germany and exactly as pictured on the photos - white, clean and beautiful. The keycaps are Double-shot with very rough and sharp edges on the bottom, which makes handling them loose very painful.
The PCB looks as if it has some corrosion of sorts, but the board works fine. Too bad it has the MY switches, though, which makes it unusable for me (also, 2-key-rollover).
