Diamond goodness

I purchased this section as a replacement for the two cracked sections (and one that is completely missing) I have for my 1st run 530. A conversation with Speedy a while back convinced me that this was the solution to the cracking issue (only one of the creacked sections is due to the defect, the other cracked when dropped by my daughter).
The fine nib is very smooth and wet, with just a touch of tooth.

A fine nib

Easy to replace, fit without troubles, nice storage container for the spare nib, and the nib writes beautifully. This is a European fine, not an Asian fine. Suits my writing style to a T.
