The original '69 console in my car along with the 1 or 2 used ones I have appear black throughout (at least where the cracks are around the ashtray area).
Due to the cracks in the originals, I recently purchased a reproduction console shell. It's very accurate from what I can tell. However, the grain pattern (though accurate) is a little more crisp than the original, which had me wondering if the originals were painted - even the black color version. Seems if I were to paint the reproduction, it would be spot-on from a grain texture prespective as the paint would soften up some of grain texture. Also, by painting the console shell, it would be easier to match the console door and ashtray lid black gloss/tone, which again had me wondering if the factory painted the black console shells.
