i have a similar anvil ,it has a farriers clip on it .I just assumed it was a weak spot in the waist .I'll try to post pictures later .someone welded mine to a large steel post and plate. add a big old chuck of chain to the base and it woorks great. Smokey
My first anvil purchase is a colonial anvil with the 5th toe. it does not have the ledge behind the horn like most anvils . if you get it in the light just right you can make out a S on the side . figure that means Sheffield ? Cliff
