@captjoe06 - I hit my old wire charcoal baskets with a wire brush, just to knock off the heavy surface rust. They will be fine to use. That color green is really unique. I would describe it as a Christmas Ornament green.
Nice score. That sucker is bright! It will be interesting to see if it gets darker when hot. How big is the hole in the kettle? Big enough to make it into a spot to put probes through it with a grommet or something similar?
