The Ju-52 would make a really nice addition, especially for the Invasion of Russia add-on. Having a few sitting on the runways in France would be nice as well to add some more immersion. So many photos of Luftwaffe airfields have these sitting in the background. Even it it wasn't flyable, having them for escort missions would be nice.

"Don't let the 52 get shot down or this week's schnapps ration is lost. . . and your new Commanding Officer with it."
