The object was shipped to Berlin from Barcelona. A Nazi loyalist professor of engineering was tasked to the investigation of the object, as several Nazi officials knew of Hitler's taste in the esoteric and hoped to use the object to win favors discreetly.
The professor, in turn, passed of the chore of understanding 348 off to several of his advanced students, most importantly, Ernst Pfaff. Pfaff, while writing his doctoral thesis on analytical engines, recognized several analogous components in 348. Using analogy and intuition, he pieced together the many pieces of the object. Confused of the function of the object, he looked into the history of the object. Quickly learning that the object originated in Mexico, he wrote to a student of Arthur Evans in Gottingen.
This archaeologist specializing in Mexican history recognized many of the components of the object as writing tools common to the Aztec. With their combined insights, they found that the object could both read and write the written system for Nahuatl. Their understanding of Nahuatl was too limited to recognize that it could write intelligently.
By the time they had begun to adapt the object to write German, the Soviets captured Berlin. Neither scholar was heard from again. The Americans, as an extension of Operation Paperclip organized by David Packard, secured all advanced German computing equipment, including 348.
