Interesting question and the answer would, I am afraid, be a little too revealing. Suffice to say, there are some configurations of first gen Carrera that I expect exist, but have not yet come to light. Cryptic enough?
Failing that, copper text 2447 Ns (that's plural N, rather than the NS panda). I know the dials exist because I have seen them at the TAG Heuer HQ, albeit only mounted on a board, but not yet in the wild.
