Packed away in a box somewhere, I have two or three toy gliders from Germany, or possibly from West Germany. They’re quite attractive and well-made. The fuselages are made of vacuum-formed plastic; two halves joined together. The nosecones are, IIRC, rubber. I don’t remember if one had a rubber motor, but I do recall that they came with a plastic stick with a rubber band on it for launching. If one of them had a rubber motor, I think it had wire landing gear. But again, I don’t recall. The wings and tail surfaces were wire frames covered with plastic film. They were white with bright colours. I recall one has red and green trim decals against the white base. I believe they were sold in cardboard boxes, and that the wings could be removed.
I could dig through boxes in the storage unit, but I’m just curious what the name of the company that made them was.
