I found this in my grandfather’s barn where I had inherited a 1904 Soderfors anvil and forge a few months before. I’m not sure what it is. Not a regular Blacksmithing hammer. The handle hole in my opinion is too small for a striking handle. I would guess it is just for a holding handle like a top fuller or punch. I have two - one is a 3lb and one is a 3 1/2 lb. one of them has a touchmark, but I can’t make out what it is. Any help would be appreciated.
