Cheyenne Tailgate Trim Question

Sorry, I tried to search threads but it only confused me. I have a 72' K10 Cheyenne with options Z84, BX2 and B85 on the build sheet. My restorer is working on my truck in Sacramento. He said the tailgate trim that spells the words "Chevrolet" looks black and not wood grain. I am certain it is the original trim piece. Is it possible that it was black from the factory; maybe it was wood grain and then faded dark over the past several decades? I will post pictures.
