When I was young, everything was on a budget. Paper models were the cheap alternative to plastic models.
I did build a large number of models, also from the former East Germany, mostly Rockets and spaceships, but unfortunately I don’t have photos of them. Below are some models I built from Schreiber.
A small model was the Junkers F13. A small airplane, in fact the world’s first metal airplane, used for the first Lufthansa airmail services.
Another model was the “flying ship” Dornier Do X, at the time (1929) the largest seaplane powered by 12 engines.
I built a number of ships, among them the NS Savannah, the first nuclear powered civil ship, a tug boat that had some ballast in the underwater ship and with sealing with transparent paint could actually swim, and a few others, of which I did not find pictures of. The steamship Franz Schubert below I built at my grandmother’s place when I was very young, between 10-12 years old.
You could can make paper boats water resistant and even fit a remote control (see the video below). But I never went that far.
And then there were buildings and castles. We built a lot of castles. This friend of ours, he had almost all of them. I myself I had Lichtenstein.
