I have seen it in the Levengers Catalog and currently the RB is the only one available.

I am interested in the FP in medium nib.

Any thoughts on the performance of this pen and any measurements ?

My last experience with a CS 58 was less than good because the flow was stingy for my taste. The nib was not glassy smooth and borders on scrathy (as in extremely toothy) even though the tines are perfectly aligned.

Any thoughts on this special Levenger Edition ? (hopefully positive ones)
