In December 1930 there was also the birth of the Internazionale model,[1] also a back lever filler, who was used also for Le Duo Moderne. The pen, produced in four sizes and in a broad mix of colorful celluloid, has a wide metal band between two rings, decorated with a Greek motif. In the same period several pens intended for the export market, particularly for the French market, were made; they are in general quite similar to the Duplex, both in style and for being lever filler.
