This anvil screams when struck. Hammer rebound is great. Can't get over the sound it makes. I'll definitely have to pull some serious moves to quiet it down some. I've attached some pictures of the horn damage after I cleaned her up a bit with a wire wheel.  Still having trouble uploading pictures, but I'll throw up some before and after cleanup shots soon. For now, here's just a few from the day before and during cleanup.

That horn damage shouldn't cause any problems.

Not half bad!  Congratulations!

Sweet anvil! That spot on the horn shouldn't be an issue of functionality at all, but it is in a place that could be welded withought hurting anything. UNLIKE the face of the anvil.

As a high carbon cast steel anvil welding on the horn will require preheat and slow cool (preheat to BELOW the draw temp of the face!)

Both anvils look pretty good to me. I hope you're passing an excellent time forging on them.
