The problem is I need the topos for the time period...things change in 60 years. And more importantly I also need building locations and road networks, as well as the layout of the train tracks. The reason I need the detail is that I am a game designer for Critical Hit Inc and my next project is covering the adtions at Krasni Bor. We pride ourselfs on the level of detail in our maps (each hex=50yds Squad/gun/tank level). and I am struggeling to find good detailed maps of the area and the time.

as far as search engines I have used-Goggle for both spanish and german and I have also used the Spanish engines Abacho.com and Terra.es
