I jumped on this one because Pelikan no longer makes anything near the range they used to have, both in terms of pen shapes as well as nib types:

The 400NN was developed after the 400N was a “neu” version of the old 400, which looks like the modern M400. The finial and knob gradually got rounder, finally arriving at the rather cigar shape above. The binde of the vintage tortoise variants also varies far more in colour and evenness compared to the modern browns on the M400 and M800 pens; mine shades from dark brown to as light as yellow and green in some places — to my eyes, much closer to a tortoise’s patterns than the rather averaged-out modern colours!

It arrived clean but definitely shows signs of age and wear: the finial is rubbed fairly smooth, not to mention the brassing on the clip and the cap band. The nib itself is in excellent condition though it has a slightly stubby quality, which is a sign of long periods of intense use.

Indeed, it was the nib that attracted me to the pen. Pelikan used to make a range of italics and obliques and “ballpoint” (Kugel) sizes with different sorts of tipping, and this dates from the era of pre-ballpoint carbon papers, when special nibs were made to withstand larger pressures without flexing. Mine is a DF (Durchschreib-Fein) nib, or a manifold fine, and comes in almost as fine as my Japanese pens — no modern Pelikan “fine” here! It is a single-tone 14k gold nib and has shorter tines. Unusually enough, it also has two breather holes.

In writing on Fabriano paper (below), the pen gives a very pleasant sort of toothy feedback — a sign of wear — and yet absolutely glides along on Tomoe River paper. As with my other Pelikan fines, it writes on the drier side, but is wet enough here to show the shading in Oku-yama. The pen itself is light to hold, as one would expect from the rather small 400 size. And while it is very firm, it does not feel like a nail…

A size comparison (in featured photo) places the 400NN as intermediate between my M200 and M620s, which is only to be expected. More delicious photos in better lighting here:
