My anvil is homemade out of 2 pcs of rail road iron, 6x6 I-beam for bottom and 10" Jr I-beam for stand. Might not be as heavy as yours, but works good and is easy to move. If we had a real anvil, would probably mount similar. Put 2 pcs 1/2" flat steel under each end of 6x6 Ibeam to stabilize and lift Ibeam off floor for 2 wheel dolly to slip under. We used 10" Jr Ibeam for stand, then welded a piece of rail road iron on top for anvil. Then we made a rack to hold another piece of rail road iron to lay beside, upside down for a larger flat surface. It can be lifted out if needed.
Will see if I can get some pictures.
Well, maybe pictures someday. We started using a Linux operating system and sometimes we can find our phone when we plug it into the computer via usb and sometimes I can't seem to find the way to make them connect.
