Help me ID this anvil please :)

This anvil sits in the back of my shop, & I want to try & buy it from my boss but before that, I want more info on it. I see no markers marks, its 277LB/126KG The weld seam is up the middle from bottom to top.










Looks like a Soderfor’s to me. But without any markings is really hard to identify wich really is.
I buying 2 beasts soon but i dont know what brand they`re too, the current owner put a lot of oil in the anvil and i cant see any markings too, ill post some photos asking for help soon!
