After quite some time of absence on this forum, I was scrolling through some old threads. In my opinion this decal has some features I like to see in original decals, but I have never held one in my hands though. I am curious why you think that this decal is a locally produced Dutch variant.

I do not want to draw any definite conclusions here, but the similarity of the decal on your helmet with this Walloon recruitment leaflet is striking in my eyes.
