In 1982, the old model 400 was re-introduced in its typical black/green alternating stripe pattern under the name of Souverän ("sovereign") M400, which was the beginning of the renaissance of classical style fountain pens. M400 was the great success, which led to the introduction from 1983 to 19875 of models Souverän M600 and Souverän M800. M600 was a higher line of M400, but in the same size as M400. Technologically and physically, M800 was a higher line of M600. M800 was not merely a larger version of M400 or M600. Worthy of the flagship model of Pelikan fountain pens, there were several changes/upgrades in M800.
