Until norbyte is able to retrieve an item DB, you must go to items list and look every single item (yeah... Long process) until you find thé one you are looking for. Then it is not written as its in game name but its ID, on the "stats" line. so you must guess which one thé right one.
Thén, if you manage to do all this, you have two ppssoble ways

1) modify owner and slot of thé original item, to match an empty slot of thé inventory of one of your char
2) modify à preexisting item of your own inventory, using both ID and current template of the item you need, mostly à book or an item without any complex nodes, assuming your item is not à complex one itself (book, stones, crafting materials...)
