Well on the condition it is rather nice, Im sure I could use that horn for a thing or two like I do my tinsmiths spike.
What bothers me is when you look close, the bick seems to be welded on check image 7. I could be wrong and it could be a good weld.. but when I think about THAT much leverage out on the tip I worry. Then I look at the poor heel and hardy, why out of THAT much length did they put the hardy on the thinest portion! Its almost like they were drawing out the heel and found out they had too much steel and left it there. I think I would snap that thing off with a few strong blows to a hardy then Im out 2grand! ( not that I would EVER spend that on this poor thing)
Edit: Woa! Just took a good look at the heel in image 8, does anyone else see a diagonal line there... like the heel was welded on??? This might be where your crisp edges are from, a total regrind. We joke about Frankenstein stuff but I think this one takes the cake, I dont know but Im guessing, Horn, Heel, Base were all different parts and maybe, MAYBE the main mass was another anvil to start. Im willing to bet if you turn it over you will find the exit to an old hardy hole in original heel, Im so curious now I cant stop thinking about it!
