Yes it is. This is one of the models that got me really into converting.
Lots of pieces and such coming together to make a cool model. It dates back to 2002 or 2003, can't quite remember, and was part of Khorne beastmen army.
Head is from the beastmen standard, lower jaw from the ogre head on the base, not sure what I was thinking at the time with the orc mouth. A tyranid limb and some plasti-card on the other limb for sharp pointy things. And the big hand can't remember where that came from. The metal body was left over from one of my old minotaurs.
