What are these wheel-chocks made of and what color do they most probably have? I found a new hobby of mine: Colorizing black and white photos. My first project was a B-17 and now I'm working on a He 162 Volksjäger. The plane is on ground and fixed with wheel-chocks.





Now the question is what they are made of and what color they could have. Maybe there is a specialist for german aviation in WWII out there.
Those chocks were made out of wood; I am guessing that they were unpainted or painted a bright color, for visibility. Today, they are made out of rubber or a synthetic. Rubber grips better than wood, but the wood chocks were most likely made out of wood, to preserve the rubber for the war effort.
