I've just fixed up a New Style Duofold, it has a Sheaffer nib which writes well but looks a little small for the pen. I would like to fit a more original nib if possible.
I've seen a few AFs with 35 nibs, which is supposedly the senior size. I understand that the NS would have had an un-numbered nib but does it take the same size as the later aerometric standard/demis or the seniors?
Thanks for any ideas
John
