I'm Bill from Mechanicsville, VA and I just recently purchased a Hill anvil (163#) that I guess is fairly rare. It is in great shape for a nearly 180 year old anvil. There is about a 1/16th oo an inch swag in the face and various dings in the surface but other than that it is in quite good repair. There is a fellow here locally that has a machine shop and he could reface it I am sure but what say you guys? Will that kill the value of a rare piece? I plan to use it later in the summer. Should I just blet sand it. Does the "belly" in the face help or hurt? Just hoping to learn a little more about it.
