Hi all... This may seem obvious to some but I have a mint 140 and I'm not sure what the little hole is for on the fine nib. Is it for adjusting the ink flow? By the way this is my second 140 both are striated green (what else can a Pelikan be) and both are gorgeous writers.

The hole is a vent, to facilitate, but not adjust, ink flow.

Thanks for the reply. The hole I'm referring to is not the hole at the base of the tines but a second slightly larger hole further down the nib. There appears to be nothing beneath only the top of the feed. Judging by the finish on the hole it looks like it was manufactured that way.

Usually, there are one or more letters at the base of the nib (the part closest to the section) marking the type of the nib. What is written there on your nib?
I have an old Pelikan 400 with a DFF nib, that also has two breather holes. DFF= Furchschreibefeder Fein=fine nib for making multiple copies with a carbon paper. A very strong, stiff nib, with a slightly curved shape (the tip and the tines are curved downwards). Yours looks very similar to mine, so it might also be a carbon copy nib.

Thank you for your comment rlukcs. I've looked at the nib and your spot on. It does say DFF and it is rather firm. I suppose that due to the nib being firm (the tines don't flex) and fine it needs an extra breather hole to facilitate ink flow. I usually go for flexible nibs but with a fine I use it to make notes and fine is perfect. I've really got the Pelikan bug. Although I specialize in collecting Wyverns I never use them. By the way my every day (work) pen is a Parker Duofold Senior with a medium oblique. I'm not too keen on Parkers as they are a bit common ! but the Duofold is certainly a classic and a real workhorse. I use my Pels at home and use the 140 fine most of the time. Thanks again and I'm sorry if I'm rambling a bit.
