Never WAS a Bran Redmaw model?

I remembered seeing something online when IA 11 came out, but then never really saw the mini...  Turns out they had one as a WiP and then discarded it.  So, no official models...  I guess I'll be fine using a "Standard" Wolf Lord mit axe and one of my ancient Rackham Wolfen to represent him in Lupine form...  Neat I guess :-)...  Am a bit curious what sized base is recommended for the "Monstrous Creature" form...  Not wanting to be unfair, and as he more or less is ONLY a HtH creature, the larger base would be an advantage I think...  As it happens I have a few...

Have to put a kilt on the "Wolflord" form as well I guess...
