I have three Pilot Bamboos -- silver, black, and maroon (if that's what they call it.) I've noticed on two of them, the nib reads "Pilot," but on the third "Namiki" (I can't remember which of the pens it came from, as I switched the nibs around a little many years ago when I got them.) The nib/feed/sections are identical on all three except for the names engraved on the nibs -- in fact, the Namiki nib and one of the Pilots are both F, so you can't get closer than that. The caps on all three pens read "PILOT." Obviously, Pilot and Namiki are the same company, but this seems very curious to me. Thoughts? I confess part of this is my wondering if I'll have a problem with the value of one if I want to sell them all someday, but mostly I'm just interested -- including for future reference if and as more Pilots might come my way. Thanks!
