In 1933 the [[Rheingold]] series was restyled and produced in four different sizes; models were given the numbers 1911, 1913, 1915 and 1917. These were joined by a few second-tier models: the 306 produced in black, blue and pearl, and the 205, an economic pen, also called ''Seneca''. Was also produced a stilographic pen for technical drawing, numbered  as 560A. In 1935 was intrduced the luxury model [[Präsident]], with the body equipped with a transparent section and a new filling system, then used also on [[Rheingold]].

Negli stessi anni il sempre maggior successo del nuovo [[caricamento a stantuffo]] spinse anche la [[Soennecken]] ad adottare questo sistema con il modello 1306, realizzato secondo un progetto estremamente robusto in cui il perno ed il dato di fissaggio del pistone erano realizzati in ottone. Nonostante questo le nuove penne della [[Soennecken]] vennero commercializzate ad un prezzo più basso degli equivalenti modelli della [[Montblanc]] e della [[Pelikan]]. Nello stesso periodo venne commercializzato un modello economico per studenti denominato [[Soennecken S4|S4]], chiamata anche ''[[Soennecken S4|Sutterlin]]''.  

During those years the increasing success of the piston filler introduced by [[Pelikan]] pushed even [[Soennecken]] to adopt this system with the model 1306. It was built ​​according in an extremely robust way as the fixing pin and the piston were made ​​of brass. Despite this new system [[Soennecken]] pens were marketed at a price lower than equivalent models of the [[Montblanc]] and [[Pelikan]]. At the same time was marketed an economic model for students, the [[Soennecken S4|S4]], also called ''[[Soennecken S4|Sütterlin]]''.
