The top I ground with various c-thru flex discs on my angle grinder, followed by polishing and buffing. The top plate is so hard that files skate (typical of Trentons), but the horn you can file, then sand.

Also, don't expect or try to grind the top plate flat. It just isn't necessary. I ground the edges to the radii I prefer, removing or smoothing almost all nicks, and took out any nicks in the top, although I should say I started out with a fairly pristine anvil. If you have a rougher surface with cuts and divits, it might be wise to have a welder who understands refurbishing restore it.
