I'm putting this out there for others who might not be aware of this fact. Please note that the converter is bought separately but even it can be taken apart in no less than 5 pieces, simply by unscrewing the metal sleeve at the end.
As for the pen itself, the nib and feed come out easily by pulling. They are friction fit and also keyed so that there's only one way in which they go into the section. My nib is stained and simple scrubbing with soap didn't clean it. I just don't care so I won't bother trying with more powerful substances.
I just love a fountain pen which is easy to disassemble!
