My grandfather bought this secondhand about 35 years ago, my Nana is now selling most of her things to move into a smaller house, this has been living in the garden as a patio ornament all that time.
There doesn't seem to be any maker's mark, though it's exposure to the elements has left the surface pretty rough (it's obviously iron)
I'm not sure how heavy it is but I regularly carry a 17kg dog and this thing I barely managed to get a cm off the ground for one second.
All my Nana is interested in is what we should advertise it as (anvil or ASO) and how much we can get for it but I'd just like to know a bit more about it if anyone can help, a friend of mind believes it is probably cast but as I said, the weather has removed any seam lines that may have been present.
Also I hit it with a hammer and it dings, on the middle, the horn and the back
