Item code for Irenicus' mask

Since I'm playing a monk i have 10 int and 10 wis, so Ellesime doesn't give me Irenicus' mask at the beginning of ToB. I really want to try to have him as a NPC however. What is the item code for his mask? He's supposed to show up if you possess his mask, right? Is it necessary to set a quest trigger as well?

well, i had the right dialogues, but i guess some other mod i had intalled spoiled it to get me irenicus mask ...
ist there a way to get it via cluaconsole createitem? what i'd need is the right icon code to give it a try ...

thanks for your help
