This is from the Mr. Pen website, under the Parson's Essential section:
Italic or conventional nib options (Note Broad and fine Italic is created from a medium nib blank and is marked 'M')
Medium italic 1.0 mm approx on the broad stroke, Broad italic 1.3mm approx on the broad stroke. We now offer a fine italic at about 0.85 mm on the broad stroke also The Fine Italic is slightly cursive as it is cut at the tip of the pellet.

This is about the italic nibs, but the cursive stub is probably not that much different; perhaps a little narrower. Mr. Pen has a Live Chat function where you can ask them directly.
