In the summer of 1923, Windischgraetz came into contact with prominent German nationalists Erich Ludendorff and Adolf Hitler with Bethlen's tacit approval. German nationalists shared Hungary's animosity towards France and were eager to collaborate on clandestine operations. It was at that point that Ludendorff (a retired Prussian Army General) revealed to Windischgraetz that German industrialists from the French‐occupied Ruhr had financed a plot to counterfeit French francs. While the technical aspect of the plot had been nearly completed, it had to be abandoned due to the warming of Franco-German relations in the prelude to the Locarno Treaties. Ludendorff then offered Windischgraetz to execute the plot with the use of the left‐over equipment. German engraver Arthur Schulze was sent to Budapest, he in turn helped procure printing machines in Leipzig. In the meantime, Windischgraetz's secretary Dezsö Rába arranged for of special paper to be shipped from Cologne. The materials were transported aboard tugboats navigating the Danube River and in sealed railroad cars from Bavaria.
