Pilot Nib Designation

[Ted F]

I have a Pilot 823 with a 14K Gold Nib. It is marked F and has the number 15 above the F. What does the number 15 indicate?

#15 is the nib size. Same as bock designates it's nib sizes as #5, #6 and #8.

 

This should help you see the various pilot nibs: http://kmpn.blogspot.in/2010/04/pilot-nibs.html?m=1

It's like Mew says, #15 is the size of the actual nib unit. F is the "size" of the very point of the nib.

Thank you. That was very helpful.

But remember also, that each pen company generally has its own nib size standard so a Pilot #15 nib may not be more than twice the size of a Jowo #6 nib.

Actually,

Pilot #15 = Jowo #6 = Nib on Visconti HS

 

Pelikan M1000 nib = MB #9 nib = Bock #8 nib

This is the pen I got. It writes beautifully.

I got the same pen a few weeks ago. Pilot Amber 823. It's my favorite pen... it writes beautifully and its large nib makes me wish the rest of my Pilots had #15 nibs.

 

How do you feel about having to unscrew the back? I couldn't stand that. I saw this video: http://blog.gouletpens.com/2013/03/removing-vacuum-filler-pen-o-rings.html and followed those instructions.

 

Now my 823 works without having to unscrew the back! It's wonderful, as that was my only complaint about the pen. I haven't had any side effects after removing that o-rings --- but I don't go jogging with the pen or anything! I also store it vertically or horizontally during transit. But no problems. No leaking or anything like that.

I think this will give you an idea of nib size.

 

Left to right: Namiki #50 nib, MB 149 #9 nib and Pilot #15 nib.

I have a TWSBI with the same vac system. When the end is screwed in your cutting off the ink supply except for ink in the feed. When you loosen the end you're opening the ink chamber to supply ink to the feed. I don't find this a problem (it becomes a habit) and I'd rather not take parts out of a pen.
