Brandon, it's great to see you hunting down this information to satisfy our curiousity. Wish I could lend a hand, but all four of the 2000s that have passed through my hands have been pretty normal and boring (aside from the one I still own right now - it's been converted to an eyedropper, and it's apparently a hybrid model featuring a clip silkscreened W. Germany on it, but with a barrel sans "L" on the bottom). By the end of next week, it'll be even weirder, as a good friend and collecting buddy is sending me a replacement nib for it that likely predates the pen by 20 or 30 years (it's a nib from a 27/30 series).
Hey manolo, is that set engraved/silkscreened anywhere with the Gulf logo or anything?
(Thinks to himself, "How cool would it be if there was a little engraved Gulf logo on the top of the clip, or a color logo silkscreened on the top of the cap?" Oh, how awesome would that look next to a die cast model of the Gulf Porsche 917s from the Le Mans days?)
No, only plain "GULF" engraved on the body of fp and bp. No logo. I don't know the history of the Gulf company, but the pen seems to come from the french market, as the paperwork is written in french. I bought it from a man living in Mallorca, who was in turn selling the pen from a friend...a long history. A bold stub that writes beautifully.
