Now more than one fountain pen

Pelikan are my favourite fountain pens too, for the same reasons you like them. I have over 100 vintage and modern fountain pens of which six are Pelikans, both vintage and modern.
 
It's been a while but thought you might like to see my latest pen acquisition. Parker Urban steel cap and body, plastic grip section. Takes standard Parker cartridges but I refilled an empty cartridge with Diamine Onyx Black ink using a syringe.

Bought it from "Fountain Pen UK BST" on Facebook for less than a tenner. Unusual shape where the thinner waist kind of fits into the hand nicely. When I first got it it skipped sometimes, especially when starting writing. I smoothed the nib a little and that seems to have cured it plus it writes with much less feedback.





 
In general Diamine inks are brilliant, but Jet Black is not one of my favourites, it's just not black enough. I've not tried the Onyx Black, but I am a fan of Herbin Perle Noire, it's very black, has some water resistance, but is also extremely well behaved.
 
For a black ink that's properly black, as opposed to dark grey, I like Aurora Black. It's comparatively expensive, but it flows well, and seems to lubricate nicely, which is handy if you have a pen with a nib that has a bit more feedback than you'd like.
