That map is a great idea. I think that size mayby around from Oder on west (we have now "Berlin" map with small part of modern Poland) to before-war Polish-Soviet border on east (west Ukraine- "Lvov" map, Belarus, Wilno/Vilnuas region). In north part it could include East Prussia with Koningsberg/Kaliningrad, and on south: of course Silesia and Polish-Slovakian border in Carpathian mountains.

It will be not only for 39 scenarios: for Barbarossa begin, and 44-45 (winter ofensive) too.

So, good luck.
