This is a very simple paper model, made in one of those lost moments. ;o)
The Sword of the Phoenix appears in the Dutch X-Men comic #303 ("opkomst en ondergang van het Shi'ar-Rijk"; originally "Uncanny X-Men" #479 "Rise and fall of the Shi'ar Empire")
The parts for this papercraft model (and lots more!) are available from my papercraft webpage: [link]
Have fun building!
