Neat, but I think you'll have problems with the way the little anvil is atached. Also is it cast iron or cast steel? Even with the extra wieght the cast iron will be so soft as to be next to useless.
I've made out pretty good with a couple of Harbor Frieght 110 lb. Russian cast steel anvils, there not a Nimba, but then I paid 89$ each. I did have to do a good bit of grinding to clean them up, and one I cut the horn off for a bladesmith anvil but there holding up pretty well. Harbor Frieght doesn't carry them online anymore, the two I've got were from there store and they only had three. You would probably have to call to see which location has any left.
