'What sort of nib did he use, when he did write?'
'A "J" pen, my lord.'

The black metal bit at the bottom of the picture is a nib, a bit like the nib of a fountain pen. Instead of being "fuelled" by a tank of ink like a fountain pen nib, it slots into a pen-shaped holder and is dipped into ink - hence the term "dip pen".
William Mitchell brought out a series of alphabetically named nibs, of which the J was a huge hit. If you look carefully you can see a capital letter J in silver on the black nib - echoing the one in the bottom right corner of the box.
Sometime I'll put up a picture of how it looks in a holder and what the writing looks like (although the holder, paper, and ink will all be modern).
