The NameString-Pointer points to an Integer-Array which holds encrypted Name Strings.
There's a Function @

7840 which is called to decode the Strings.
GWCA++ has an implementation of it.
However there's no Solution for AutoIt to decode the Strings.
BTW: the list that has been posted here (Global_Items.au3 ? ) doesn't hold all known ItemModelID, I think it holds less than 0.1% of known IDs ... furthermore there are some wrong IDs inside.
