As the 1960s continued, several variants were produced, and cheaper lines of [[hooded nib]] pens. The [[piston filler]] system with ink reserve mechanism remains as distinctive.  From [[1961]] were also introduced  [[cartridge filler]] models, maintaining the ink reserve through the use of two separate cartridges (see patent {{Cite patent|DE|1215025}}), as for the [[Duo-Cart]] of the [[Aurora]].

Negli anni '70 la produzione di stilografiche venne sempre più orientata alle linee economiche per gli studenti, restando comunque marginale nelle attività dell'azienda che dal 1972 si specializzò in macchine copiatrici e lavagne luminose. Nel 1990 la ''Geha'' venne acquisita dalla [[Pelikan]], restando comunque una produzione di penne con marchio proprio, all'interno di quella della [[Pelikan]].
