I've been lurking here a bit, and I finally decided to join up.
My grandfather left me some fountain pens (among other things), and I would like to restore and use them.
So far, I have a few Vacumatics, a Sheaffer, and a couple of Esterbrooks too, but his favorite was this one.
It doesn't presently work right now, as the diaphgragm is broken.
Thank you, ken
