I have a Parker 180 (with double sided nib, not the classic). How can I remove the nib from the section? Is it a screw in feed?
Thanks,

The 180's nib unit pulls straight out, usually with a slight wiggle/twist action. It's not as easy as, say, a 75, and there is a slight chance of breaking the feed (which is brittle and not well supported by the short nib). The nib and nib stabilizer are held to the feed by a transverse plastic peg that is heat-flared to secure them.
