This anvil belonged to my great great grandfather and has been in our family since approximately the 1930’s. He was a blacksmith by trade. My father grew up on a farm in austell, ga with a working blacksmith shop that we have retained many of his tools. My dad recently started trying to find the origin of this anvil and I wanted to see if some of the experts on this site could lend a hand. It weights 78.2 lbs, on one side has the numbers 0, 2 or 3, 25 or 35, On the other it appears to read the London Sheffield. Any help would be appreciated
