Well, it's certainly not a Peddinghaus anvil, but with a little work, it's a good start.
First of all, like the others have said before me: by all means, if you can find a real anvil, buy it! But, if you can't find one or you are strapped for cash, this cast-iron A.S.O. will work for now with some modifications.
As soon as you buy it, take an angle grinder and take that **** paint off of the face and horn. Then, round off the horn a little bit - it should look like a horn, not a duck's bill. Next, get at least a 1/4 inch mild steel plate from your local hardware store or welding supply shop and use JB Weld to affix it to the anvil. This set-up isn't the greatest, but I only use it for knife-making so it works for me.
Good luck.
