I've wondered the same thing. We haven't gotten a great batman either. Don't know if it's a coloring issue? I asked BK to do one for me but he wouldn't saying the colors were just too off.
Go vintage, build an old pepsi GMT, andit'll be way more accurate. The gen is white gold anyway, just knowing that would bug me..
If they could make tungsten carbide reps though, that would be sweet. Would make it feel gen in hand for the most part. They would need all sorts of new machinery though, so it'll never happen
