1899 letter, what type of pen?

[Nightjar]

I found this letter at an antique fair, for about the price of a flat white. It's from Lord Walsingham (Thomas de Grey) to Lord Amherst (William Amhurst Tyssen-Amherst), both Norfolk landowners. Walsingham proposes reintroduction of the Great Bustard on their estates...

 

But my question: is this a dip pen? [It certainly gets paler towards bottom, but I guess that might be differential fading.] I think (?) dip pens still very widely used at turn of century.

 

The letter continues for another two pages; and the bustard story continues too, and is fascinating, but I'll spare y'all that...

Guess 1: dip nib (presumably cut like a J-pen, even if the thins look too thick).

Guess 2: a quill.

But of course it could also have been a fountain pen...

 

Have fun!

Thank you @Claes! 

 

My un-expert gut feeling is dip nib. But a quill: that would be very appropriate!
