Fountain Pen Revolution - what other pens (not FPR) does their #6 nib unit fit?

[tde44x]

I was wondering if anyone knew if their #6 nib units (integrated fee) fit any other pens? Was thinking their ultraflex nib might be nice in other pens.

I haven't come across any as yet - the threading on the nib assembly is *not* compatible with pens that take JoWo or Bock assemblies.  I think it may be a proprietary assembly, custom designed by (or for) FPR.  Sadly, the shape of the nib itself means it won't easily fit into those nib assemblies, either.  

 

I'd be interested to know whether anyone else has an answer to this question?

The nib itself is pretty standard. In principle any FP taking a #6 should accept it. I've used them on Jinhao and Baoer pens without any issue. And as far as I know, others have also in many other #6 sized FPs.

 

If you want to use the nib in an FPR housing, then, I don't know, but, considering all, I would rather get the nib (not the nib unit) and substitute it in whatever other nib unit came with the FP I wanted to use it with. Actually that's what I did with some of their #5.5 nibs, though I had to bend them somewhat to fit in a #5 unit, but you should not have that problem with a #6 on any #6 unit.

I suspect the O.P. is expecting (or imagining) the feed in the FPR #6 nib units will be tuned to adequately support the ultra-flex nibs with ink flow, and don't want to swap a nib to another "might be nice in other" pen to benefit from the body design (or material, integrated filling mechanism, etc.) without separately sourcing an ebonite feed, for example from FNF, to match.

I don't think there's such a thing as a "pretty standard" #6 nib - JoWo is different from Bock is different from FPR, etc - and there are some noticeable differences between FPR's offerings and the two "industry standards" I'm referencing.  Just to give you an idea (and to experiment with the "drag and drop" copy option), here's a couple of comparison photos.  The JoWo (top) and Bock (bottom) nibs tend to wrap more tightly around the feed towards the back end of the nib - and the couple of times I've tried it, it's been difficult (if not impossible) to fit a FPR nib into JoWo or Bock feeds.

It really depends on the fountain pen you're considering as to whether it will fit. The FPR nibs appear to be thicker than Goulet, Moonman, or Penbbs nibs. I've tried fitting their #6 nibs into a Moonman C1 and Penbbs 456 and that didn't go well with the stock feeds. I read in another thread that someone cut an ebonite feed to fit an FPR nib into the 456 so that might be an option.

I managed to squeeze an FPR #5 nib into a Moonman M-2 pen, and it works fine.
