Update:
Just off the phone with them. I'm getting them in graphite powder coat (which is their dark shiny finish - but isn't on their list), with the two ear spinners.
They're also going to polish the outer lip / rim so it's shiny, to give the look of a wire wheel I've seen fitted to some Morgans (dark spokes & hub, stainless rim, chrome spinner)
I'm now going to lay down in a darkened room and try and get over the stabbing pain I'm feeling in my wallet.
