Weimar Republic minus East Prussia, Regierungsbezirk Posen, Bohemia and Moravia, and Austria. Only the addition of Regierungsbezirk Posen seems strange.I can't believe noone has commented of the square-shaped uber-Germany, it was the first thing I spotted. I'm not convinced its borders are very plausible even without taking the rest of the world into account, its borders are too neat and...boxy.
