Ok, I'll give it a try. It was the number, serial number mabey that really made me want to find out more about it. I know anvils often are serialized but never thought a hammer would. If it helps I figured the orientation would be the same as the 3lb and when I look at it like that I see a face of a person wearing a hat or bandana. Cap, two eyes, a mouth and ears, haha. Looking the other way I see 2 letters BD and it looks like there is some other letter before BD.
