Hi all. I have a striated Sheaffer vac filler (short pen about 120mm capped, not a Tuckaway kind of short, but also not a Balance long either.). I think it might be a Statesman but the question is more generic:
The vac fill unit: If I pull the plunger back and then push it forward, sometimes, against a light source, I see a piece behind the plunger that moves loosely forward, and it can be pushed to the back of the pen again if I pull the plunger back.
Does anybody know what I'm talking about? What is this piece, and what effect does it have? The pen still creates a vacuum and fills, but also if I pull the rod back, little ink droplets come out on the rod too, and I'm not sure they should.
What is the best way or tool to disassemble this particular pen.
