Since I own one of these pens, I would also like to know the answer to that question.
I wouldn't have a problem admitting that this is a Waterman, except for the "Made in Italy" stamped on the barrel. When I spoke directly with Waterman, the representative said that Waterman fountain pens were only made in England, Canada, France, and the U.S. She assured me that Waterman pens were never made in Italy. It also has "Watermans" on the clip rather than Waterman, although this would simply suggest an older rather than a newer pen. I've been speaking with Richard on email about this pen for a while now, but it has me stumped (not that this is all that difficult!!) It is even more odd that it takes the C/F cartridge and has a real Bock steel nib. Please Please Please! Someone needs to solve this mystery.
