In 1947 was introduced a new line of piston filler pens with steel nib, more squat in shape, wider, with a thicker body and a flattened cap. These were called, depending on the size, with the numbers [[Soennecken 110|110]], [[Soennecken 112|112]], [[Soennecken 116|116]] and [[Soennecken 120|120]]. These were initially produced in black, but later were also introduced celluloid versions with woven motifs in blue or gray.

Nel 1949 venne introdotta una nuova linea, nei tre modelli [[Soennecken 410|410]], [[Soennecken 414|414]], e [[Soennecken 420|420]], dotata di un nuovo [[caricamento a stantuffo]] che faceva uso di un meccanismo brevettato nel 1939, in cui la manopola dello stantuffo veniva bloccata quando in posizione di riposo. Per poter caricare la penna occorreva sollevare il fondello leggermente per sbloccarlo e consentirne la rotazione, una volta caricata la penna e riportato indietro lo stantuffo il fondello veniva automaticamente bloccato nella posizione di riposo, evitando rotazioni inopportune. Le nuove stilografiche erano più sottili dei modelli procedenti e più affusolate. In questi stessi anni vennero prodotti modelli per il mercato studentesco, marcati [[Soennecken S4|S4]] e [[Soennecken S4|S6]], ed una serie di penne di forma affusolata in celloloide nera, denominata [[Soennecken 100|100]], [[Soennecken 100|100 Extra]], [[Soennecken 100|101 Lady]] e [[Soennecken 100|Schreibneister]].   

In 1949 was introduced a new line with the three models [[Soennecken 410|410]], [[Soennecken 414|414]] and [[Soennecken 420|420]], with a new [[piston filler]] system patented in 1939, where the knob of the plunger was locked when at rest. In order to load the pen it was needed to lift the cap slightly to unlock it to allow the rotation, once the pen is filled and the plunger brought back the knob is automatically locked into position, avoiding improper rotations. The new models of fountain pens were thinner and more streamlined. In these same years were produced new models for the student market, marked [[Soennecken S4|S4]] and [[Soennecken S4|S6]], and a series of streamlined black celluloid pens, called [[Soennecken 100|100 ]], [[Soennecken 100|100 Extras]], [[Soennecken 100|101 Lady]] and [[Soennecken 100|Schreibneister]].
