Hansa Gold Piston Filler - Black - Semi-Flex Nib (SB667)
Nib: 14 Kt Medium Semi-flex
Hansa was (I believe) a German manufacturer, and this is a very clean example. It's a piston filler with a very transparent ink-view section on the barrel. It's black and the plastic and imprints are very clear. The nib is 14 Kt Bock with a mountain goat. It's very smooth and medium semi-flex. All together, the pen is in excellent condition. 4 15/16,", 125 mm.
