Thanks for the advise fellas, Frosty I'm out of Jamestown California. As a tool nut interested in just about all disciplines of tool use your right I'd rather have a perfect specimen but function is by far more important than form. Unfortinatley I don't know this anvils history beyond the fact that it was my great grandfathers, he was more of a furniture maker than a blacksmith so I doubt he bought it new and he took exceptional care of his tools which leads me to believe the majority of the damage occurred prior to his ownership.
I'm also interested in it's aproxamate date of manufacture. On the side it has the Trenton diamond with solid wrought stamped in a circle below that and U.S.A. below that, on the front foot we have an upside down B with 172 right next to it and A21770 on the other side.
