This item is not available to players. The item is marked [NYI] - Not Yet Implemented - which means it is unfinished in some way (and I think we all know what "some way" means in this case, lol).
Of interesting note is that the model actually is seen in game. I discovered this by accident while cropping an image for upload to WoWDB. Check it out on Lilian Voss.
