The original one that I have is pretty worn. The infill on the Duster script appears to be silver, and neither of the outer ribs is painted. But that may have just worn off. I have a handful of Demon emblems, a couple have both ribs painted, a couple have neither. Again, hard to tell if it was worn off, or never there to begin with.
Haven't seen one with just the inner rib painted, all the ones I can recall either had both painted, or neither painted. And there's always the possibility that they were painted differently for different years or for different levels of interior trim.
Here's a bunch of original looking ones from eBay...
