Hello Michael,
Please let me know too when you find one.
I've done the following looking for a KOP extra nib-section (the bicolor 21K F or MF and not the Nagahara specialty nibs; My black ebonite KOP has the Naginata Togi M nib):
1. E-mailed Keiki Koizumi of Sailor head office in Koto-ku, Tokyo - referred me to Karen McElwaney, Sailor distributor in USA.
2. E-mailed Karen McElwaney (Houndstooth Enterprises Ltd, Fayetteville, GA) - she cannot provide one.
3. E-mailed John Mottishaw (nibs.com) - he also cannot provide one.
4. Wrote a handwritten (using my KOP) personal letter to the meister himself, Nobuyoshi Nagahara, in Kure City, Hiroshima - never got a response.

I'm looking for an additional Sailor King of Pen nib section.
What would be the best place (=best price) in Europe to look for one.
I don't think I will have much luck looking for a used one :-)
Cheers
Michael
