Thanks for all the great info.  I’ll keep researching as well. 

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
