KOSCA lever filler 18KR overlay

Beautiful and rare 1930's Kosca lever filler with Art Deco overlay. The blind cap of the pen can be removed to be replaced with an ebonite tail so that the pen can be transformed into a desk pens. Unfortunately I do not have the original ebonite tail.

The overlay is in perfect condition with no dings and no traces of brassing.

Time of production: 1930's
