Pen Community
PCA — Pen Collectors of America is a premier organization for pen collectors, with particular emphasis on vintage pens. They also publish the excellent magazine — Pennant. As a member, I highly recommend it.
The PENguin — Rick Propas, aka "The PENguin", is a major collector of Pelikan pens as well as being quite an authority on them. Rick and I collaborated to produce the PENguin Limited Edition Pen.
Paul's Pens — Paul Erano is a collector of vintage pens as well as a writer, particularly known for his outstanding book Fountain Pens Past and Present.
Suppliers
John Mottishaw — John has been supplying, repairing and customizing nibs for many years. He's a great source for many vintage and modern nibs of various styles.
Greg Minuskin — Greg has developed quite an exemplary reputation for nib work over the last few years. I'd be very happy to use one of his nibs in a pen.
American Art Plastics — Started by Dave Nishimura and Mark Hoover, American Art Plastics is a new source for special materials (e.g. Celluloid, Hard Rubber) that emulate those of the early pens. Dave and Mark have been in the vintage pen community for years and between them have considerable knowledge of fountain pens and materials.
