I received this piston-filler fountain pen, seen as the bottom-most pen in the photograph, a long time ago from my middle-school teacher. It must be several decades old, and I have no idea what its called, or what the nib is made of.
The section, barrel and piston are all one plastic unit, with no clear way of disassembling it. The feed is identical to another Pelikan fountain pen (the one seen in the middle) that is relatively new, and it looks like the nib is Gold, but there's no stamp indicating that. Is it possible that it is made of another material?
Also, does anyone know the name of the Pelikan in the middle? I can't seem to find it online anywhere.
