Yeah. Just sayin' but that guy can keep it until another fool comes along that wants it...
In a Railroad Shop, where you had a crew of strikers with BIG hammers, there may be some merit to that much mass on the stump, but for a fella that is even doing 'Smithing Professionally, a lot more than a 200 pound anvil is pretty much wasted, as anything much heavier than what is done on an anvil that size, will be done on a Power Hammer of one sort or other, if not a hydraulic Press.
I know a guy that has a 400+ pound anvil, that is swaybacked as a Tumbleweeds horse. Came out of a Railroad Shop, and he got it pretty cheap too. Told him to use it as yard art, but not until he welded a ring eye on the bottom, and gave it 3 1/2 feet of chain, anchored to a concrete plug in the ground. It would be easy to figure out who tried to steal it, as you just needed to see who was in for a hernia Operation, lately!
I tried to talk the last shop I worked in, into using the 250 pound Peddinghaus anvil that was there, as a retirement gift! Wasn't even on anyone's paperwork, so it would not have been missed. No joy, though!
When I was living in Edmonton, a fella by the name of John Cunningham, IIRC, who was a pro smith on the East edge of the city, was running a group buy of a Steel anvil from one of the local foundries. Was under $2K, IIRC, but that got you a brand new, cast steel anvil at around 250 pounds, so, competitive at the time. Kinda regret that I didn't buy in at that time!
