I recently happened in to a massive and flexible MT #6 nib. However, aside from dipping (which is do-able as it fits almost perfectly in to my Fairchild #8 holders, indicating it's a 7mm size), I don't have anything to do with it.
I've been looking for feeds and sections to house the thing and have only come across "eternal" feeds; will a #6 eternal feed work for a non-eternal nib? Additionally, there seems to be two styles:
The latter version seems to have more ladders/is a more modern design. However, since my nib has no Swan marking, I assume it's of older manufacture and therefore would work best with the former version? Or does it make a difference?
