I don't have many Esterbrooks, but I noticed that two of them have their "Esterbrook ® Made in U.S.A." caption completely faded. It is engraved in the pen body, so is still legible, but whatever paint was in it, is long gone. This hasn't really bothered me, but now I have another one (in better condition), and the same caption is painted white on it.
So the question is, how can I restore this white caption? Is it even worth to bother with it?
