I apologize in advance for my ignorance and inability to capture a decent picture to show what I'm about to describe. I have a Esterbrook nib where the feed is not aligned with the nib. When looking from the feed side, the tip of the feed is to the right of the slit in the nib. Holding the pen as I normally do the nib is very scratchy an writes poorly. if I rotate the positon of the nib to the right it writes smoothly as I would expect. Is this common? I tried to twist the nib back into position on the feed but it would not move.
