Larry, I agree on all likely not destroyed by bombing, and ground photo(s) currently on eBay.de (below) shows what appear as wooden ones, likely all burned upon the German retreat as you say. Ground fighting is also a possibility.
I find KG 3 was probably there, also some Recce units accidents but does anyone know if this was old Soviet base or built by Germans?

Any FB´s out there detailing flight-test work performed there?
