I found this website while browsing google.
It shows basic uniforms for different ranks for the German Wehrmacht in world war 2 (heer,luftwaffe,kriegsmarine,waffen-ss)
I thought I post this, the quality might not be superb for the pictures but it sure gives the idea when you want to put together an impression either for Heer or other units.
