Thanks Judson!
There appears to be a slight crack underneath but not too deep. All I did to the anvil was wire brush some of the rust off. I was surpised by the condition of the anvil. I bought it from a young man who said it belonged to his dad's and great-uncle prior to his possession. I thought it was a pretty good find for my first anvil.
I am new to blacksmithing, and actually haven't started yet. I plan on taking a course in Nov. but wanted to start to collect my equipment.
Thanks again for the help.
