I really wonder about the performance of the nib. I heard and read a lot about these pens but no chance to try.
This one is fitted with an IB nib. After some initial trouble the nib is great, very smooth, wet and good line variation. Also it's a single tone gold nib - I like those, they have a vintage vibe to me. Going to post a more thorough review in a few days with writing sample and pictures of the nib.
