Onyxia not skinnable.

After our flawless Onyxia kill last night, upon skinning her we did not acquire any of her scales.
According to this snapshot of allakhazam, from 6th of April 2005 (That is 16 DAYS before patch 1.4), the Scales of Onyxia (aswell as the HEAD which we did not get either) is on the drop table.
Following the logic of my other post regarding item ID's, the fact that Scale of Onyxia has an item ID of 15140 implies that it was in the game very early on.
Here is another snapshot, from the 26th of March 2005 (Which is a month before patch 1.4!).
It's clear from this snapshot that Blizzard already had plans for the next tier of content (BWL where the Shadow Flame actually matters).
Please help us by resolving this issue. If anyone else has any information regarding this, I would love for you to post in here to help clear this up.
xoxo
EDIT:
The Head of Onyxia, with it's item ID of 18422 (18423 for the Alliance version), seems to have been added in patch 1.3 (Dire maul patch), which should, by the logic that the server is pre-1.4, also be in the game.
