Need Help with Painting a FlakPanzer V Coelian

Hi Guys:

I just started working on the Dagon kit and I'm having trouble deceiding what colorations to use. I understand that the tank was never put into production but I'd like to use a color scheme that make sense for late in the war. I'm putting it onto the new Verlinden Ruined Church Hide Out diorama base which is a very light color - white and gray. I was thinking about making the tank Panzer Gray with a white wash to blend the tank into the walls of the building. My problem is the Dragon figures I want to use (Actung Jabo) aren't in winter uniforms and are standing on the rear deck of the tank. I use Testors and Humbrol Enamel paints. Any suggestions would be really appreciated!

BTY - The new Aber 3.7cm gun barrels are incredible!

Thanks

Charlie
