I have a pet project involving Cold War infiltrations/assasinations/demolition on Harrier hides, supply dumps etc. I'm pretty much sorted for (planned) fences, guard towers, small MG bunkers, fuel and ammo trucks etc, but what I have trouble finding are warning signs usually found around army bases in (East) German, Dutch, Russian and English (RAF ones).
So far Dutch signage and Harrier hides have been the easiest to find signage of, but I have not got a clue what to look for in Russian or (East) German.
So things like Stop!, Area patrolled by dogs, shoot on sight, mines, whatever fits, I'm pretty happy with anything.
Quality of the image does not need to be great, everything will be scaled down to 20mm scale so a bit vague isn't an issue, as are partilally blocked signs, as I can use Photoshop for that.
