1918 - today, Fountain pens from 1950

Geha was founded by the Hartmann brothers in Hannover, producing a similar product range to that of the nearby Günther Wagner. In 1950, Geha dared the launch of a fountain pen. Ist most succesfull feature was the "Reservetank", a hidden reservoir, which could be activated when the tank was empty, giving ink for another 2 pages of writing.
