Hello everybody, as I did not find any related Topic and Workflows from other hero pens don´t work, just one simple question: Does anybody know how to disassemble / remove nib from a Hero 448 for cleaning and moderate adjustment purposes? Thanks for any hint! Best, Tom PS Please: no "if you do not know how to disassemble, you might want to refrain from cleaning/adjustment ideas..." - I see your point, but I have reworked several pens already including repair of leaking Lamy 2000 and successfully reworked Montblancs. I just ask here, because the disassembly of that hero does not look intuitive and before damaging (even a pennies´ fountain pen) I just prefer to ask around some. Any friendly response is more than welcome and I do appreciate!! Thanks in advance and feixang gan xie if someone from the pen´s origin knows how to help...
