Original factory documents from a propeller manufacturer in Berlin, Gustav Schwarz K.G. These were salvaged from the factory by a friend of ours. The papers are in good condition with some discoloration from age and storage. Price is for one sheet. All are duplicates of the same thing.
This factory is near a lake and, to confuse British and American bombers, they actually created a floating replica of the factory and surrounding area on that lake. In this case, it was a successful ruse, as the allies did bomb the lake instead of the propeller plant.
