Hello my friends. I wish to inform you that it was in 1924 that Herr Karl Wittrich was born, the genius behind the GELI 1/33 scale card model airplanes which he launched in 1954 together with Frau Gertraud Litscher. Their model airplanes were the very first 1/33 scale airplanes ever printed. They designed and printed more than 65 different airplanes, all extremely attractive, detailed and not so hard to build. Fortunately, GELI kits are still available and new models are being added to the original line with the help and good offices of Herr Walter Schweiger. I suggest you to check

Best wishes to all!!
