Your presumption is correct. I am not.
It has been a bit since I had this old anvil out from under the bench. After cleaning it up. The crack wasn't as long as I remembered. After checking the rebound again, it is only dead from the Hardie hole back. And more on the side with the crack than the other. I do see another line near the midpoint of the body but I suspect that may be where the hard face is forged to the body (I included a pic)...I can use it as is, I would just hate to let the crack contiue to grow if I can stop it
