I have just added the color plates for Die Kriegsmunition der Schweren Artillerie at this link:
http://www.lovettartillery.com/Ger_Artillery_Ammo_Text_Color_Plates.html
It is a German government publication without copyright. One odd thing about the title is that is says "Schweren Artillerie" but does include Field Artillery ammunition.
I hope these scans are useful to some of you
