Could you swap a 912 and 743 nib unit?

I realize they're different sized nibs, but I heard the sections are identical. Do you think it would be possible?

I don't think those Pilot Custom models have ’nib units’ per se that can be detached and swapped around.

 

I don't imagine the feed that supports a Pilot #15 nib (in a Custom 743) would be identical in geometry to one that supports a #10 nib (in a Custom Heritage 912), so that you could just swap the nibs around and expect the pens to perform flawlessly, either.

 

I don't know how much headroom there is inside the Pilot CH912's cap for the factory-fitted #10 nib, or whether the cap would accommodate a #15 nib which is likely longer. My CH912 does not have a clear or see-through cap, and I don't have a #15 nib on hand to measure and compare the lengths of the #10 and #15 nibs.

I endeavour to be frank and truthful in what I write, show or otherwise present, when I relate my first-hand experiences that are not independently verifiable; and link to third-party content where I can, when I make a claim or refute a statement of fact in a thread. If there is something you can verify for yourself, I entreat you to do so, and judge for yourself what is right, correct, and valid. I may be wrong, and my position or say-so is no more authoritative and carries no more weight than anyone else's here.

Thank you for your input. Good point about the space in the cap.

As always, this list should help:

From what I know you can swap nib+feed between any models that share the same nib size.

Thank you, yes that is a useful page indeed. However, I just got confirmation from someone who has successfully swapped the entire section (with nib/feed) from a 743 to 912.

Remember that you will have a gold-plated trim ring on that section even if it all fits in there, while the trim on the 912 is rhodium-plated. Might not bother you, but something to be aware of before you purchase a 743.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
