The image of the pen is from Christof Zollinger. According to him, this is "a pen which is something between your 1930 and 1931 variant. It shows all the signs of a 1930 Pelikan (2nd generation characterized by straight cap top and two narrow bands), but the barrel is in two parts, the section is hard rubber and the barrel is celluloid (3rd generation: 1931-)".

It is a beautiful example of transitional version.
