WOW! Great work!

I am impressed. I think you may have salvaged it after all, at least good enough for a working spare. That looks a LOT better than i would have expected, especially in the gap. I was really afraid the oxidation would have eaten away some of the edge of the crown on the polepiece.

That said, i still couldn't sleep at night knowing it was bolted to one of my horns. It'd have to find a new home.
