Documentation on what was based where during the Cold War

[Agg]

Long story short, I like to create "free flight" missions with populated air bases and airports to at least give me the illusion of the world being alive - but I'm having some difficulties finding out what was based where in East Germany. West Germany seems to be well documented, but for the East I'm finding a lot of conflicting accounts on what was based where.

If anyone know of a reputable source for what aircraft were based at what air base in Eastern Germany I'd be very happy if you could share it.
