Reiss writes of finding "a trail of letters" in "the files of the Italian Fascist Political Police in Rome" attesting that the Nazi police apparatus had thwarted an effort by Nussimbaum to sell his work in Nazi Germany. He cites a July 8, 1937, internal note from an Italian police service showing that the service believed Nussimbaum/Bey had "tried to smuggle" his works into Germany but that "the trick was, however, discovered." "Though this does not prove," concluded Reiss, "that Essad Lev Nussimbaum's adopted name was concealing his identity behind Kurban Said, it shows that he had cause to."
