Or, more to the truth, i just need the anvil itself

Or something similar to strike.
So far this is what I have (there will be another of the same guards on the opposite corner by the way):
I'm stuck as to what to put on top of the cart/forge to use as an anvil. I thought of the "classic" anvil of doom, but not sure about size and whether it would be too big. Also thought of the Warmaster Anvil, but thought it might be too small.
As far as the platform, I'm going to finish it up by putting the dangly rune circles hanging all around the edge, but other than that and the anvil or maybe a striking plate of some kind, he's about done...
Any help appreciated!
