Thanks Jim... I suspect they're rather more modern than the airfields I'm doing at the moment, but if I ever get around to improving the more modern bases (which I do want to do) then I will start begging! :d
I have a texturing issue at the moment with the ones that I downloaded from Flightsim.com - the grass on the back of the shelters at Cosford is far too bright. Not sure whether to do anything about it or not, as it appears you can't adjust object textures by season now, so they'll always look wrong at some point.
