Just purchased this anvil, just wondering if anyone had any insight on who the maker is and around what year it was made. I know the English hundred weights markings on the side equals 91lbs(on my bathroom scale it weighed 90.7lbs, so spot on). Only thing I can make out on the other side is an “N” torwards the upper right. There is a 66 stamped on the front foot. Thanks in advance. I’ve searched for hours with every method known, flour on anvil, all different lights, crayons and pencils on paper..... nothing. I know it’s english pattern but that’s all I got. Thanks
