Hunting for decal/signage ref... WWII German Airfield hangars, offices, etc...
I'm in a pickle, needing to find or work out the type of signage one would have expected to see in or around an airfield to get some decals going. Mostly what would be painted on walls, over doors, in hangars, hallways, messes, squadron signage, maintenance areas, etc. The usual warning, danger, entry forbidden, etc I think I've got, but I'd love to find any images or just further thoughts on what should be on them text-wise or graphically (sign shape, color)... any ideas, leads, tips? Trying to get the ideas flowing by looking through ref and building up from there.
So far I've worked up danger, exit, emergency exit, safe area, caution, stockroom, engineering (I think 'technik' is right for that) fire signal, pretty standard stuff, nothing really exclusive to airfields. What have I overlooked? Finding ref's been a bear.
TIA.
