I am aware that certain manufacturers produce small-scale kits of the German Railway Plattformwagen. However, I am in the process of scratch-building one, and wonder whether there are any sheets of decal markings on the market (1/72 or 1/76 scale).

Just check out Peddinghaus stuff :

Thanks for that information ... some interesting items there.
