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]].
