Kaweco Sport Piston - AL Navy Fountain With Ink

In 1937, the Kaweco Sport fountain pen was first presented as a piston filler under the name #612 and has been further developed in many different versions over the years.

Since 1883, there have been various systems for filling a fountain pen. Today, ink cartridges are a widespread and popular filling method. In the past, fountain pens were mainly filled using ink bottles. Besides lever fountain pens and eyedropper's, the piston mechanism has been the most important and reliable filling system.
