This pen is the direct predecessor of the popular Vacumatic line.
The condition of this pen is extraordinary, almost collector's grade. The barrel translucency is excellent, and the earlier model lockdown plunger is extra clean and works beautifully.
The only thing on it is the nib, there are marks of tools near the end of the tines by previous owner/repairer.
I tuned the nib so it will write nicely as a Broad. For me the reason to keep the nib is because it's the original one for the pen as it is also engraved "Vacuum Filler" just like the one on the barrel.
If you're a Parker fan, complete your collection with this rare model in excellent condition.
Capped length: 5 inches.
