Pelikan M700 Toledo with extra-fine nib. This is the smaller of Pelikan’s two modern Toledos. It is based on the M400 body. The sleeve is sterling silver, with the decorative parts engraved by hand. It is then treated to darken the base and cover with gold the part of the design that stand in relief.
I bought the pen used and added the extra-fine nib later. Richard Binder ground the nib himself from a stock medium nib when he realized that he had run out of extra-fines. I know I got the better end of that deal; this is one great nib.
The ink is Pelikan Brilliant Black. It’s not a dark black, but a more gray black, and it’s a dry ink, so it keeps the line nicely narrow.
