Welcome to Librarium Online!
Basically life sucks, there is only war and you're probably gonna get eaten by Tyranids, have fun.
it's probably some 3 foot tall 50 lb helmet. I never understood the fascination with leaders who carry their helmets into battle rather than wear them. Not having a helmet becasue it got knocked off is one thing but marching or riding into battle with a helmet in your hand is silly. My only problem is, this looks really, really similar to that spanish sculptor who makes his own hero models. This looks like his model except reverse and with a halberd

I thought it was a horse head....
Crappy looking model to me, althought it may just be the blur factor.
