Wizards of Morcar: the unreleased metal prototypes

Here are the rare metal miniatures from the Wizards of Morcar pack.
If you think you've already seen them, you are right; infact they are shown in the photo on the rear of the box of the expansion pack.
I guess the prototypes were used to test the game and as a guide for sculpting the plastic models. Grawshak, the Orc Shaman, is way bigger than its plastic version, while the others are just a little bit taller than their official plastic counterparts. Boroush, the Storm Master, has no necklace and got a stone on his staff. The prototypes have better details than the plastic models.
Men-at-Arms were released with alternate heads and four body variants and used for Warhammer but this is the right model you can see on the back of the Wizards of Morcar box.

Please note, not all versions of the box are showing the metal prototypes, later releases show the plastic models instead.
