FW190D-11 / D-13 question

[TomcatViP]

There was a shortage of paint in Germany. I think that it was in matte 44 that they ordered all underside of fighter plane being left un-paint (unless the leading and trailing edge section).

Same for rubber. You can see on latte war picture that all service towed vehicules use concrete wheels instead of normal ones.

I hope it's what you were expecting for answer.
