The M35 I feel is a application error due to the lack of others, the ckl M42 show a pattern. The forced labor, which in my opinion is different than slave labor, is to counter the thought of " In a perfect Nazi world I believe that every decal application would have been dead on perfect--where they wanted it. That was their specifications. The fact that we see many decals off center can only be due to human error IMO. "
Wether its done in simple error or on purpose I feel we never will know but its my opinion strict "by the book" ethnic Germans were most likely not the ones appling many of these decals at this stage.
