Warlord:
The Bear and the Mordhiem range were removed about the same time - about a year ago.
The bear was available up to not that long ago but I just checked out the GW UK online store and it is not there. The entire Kislev Mordheim range seems to have been deleted as well.
Here is the catalogue listing of the wood elf beast masters

Those Kislev Mordhiem figures are fantastic, I ordered some about a month before they stopped making them. I missed out on the Bears...
I use Reaper Bears too...
I use this one for my Ogre Bulls, and this one as my maneaters (removing the axe of course).
