Ink flow through feed for F nibs vs. B nibs

[Aldo in Avila]

Given the same pen (say a modern Parker Duofold) is there a design difference between the feed of a B nib and an F nib to allow for more ink flow through the B nib?

 

Thanks,

I can only comment as to Esterbrook, Waterman Kultur and Lamy Safari/Vista/Studio pens. For those pens I see no difference in the design of the feeds. There is certainly no difference for the Lamy pens, because all you need to do is slide a nib off the feed and slip a new one on. The feed remains the same. By virtue of capillary action, the feed simply delivers as much ink as the nib uses.

Some pens have different feeds for different nibs. Others don't. I think I recall reading that modern parkers (at least some of them) use only one feed.

Thanks for the reply.
