Geha fountain pen piston and gold nib (50's)

This Geha fountain pen in black with gold color trim dates back to the 1950's (I estimate) and comes with a piston filling system and a 14k gold nib which seems to be of extra fine width and is slighty bouncy. 

What makes this pen special is that is has a small extra ink reservoir, which is opened by pushing the blue plastic knob in the feed. The ink level is well visible through the blue ink window.

The pen works well, is in used condition and there is a small space between the piston knob and the barrel. Good user pen overall. 

Pre Owned pens cannot be returned unless there is a defect that has not been indicated.
