The original material was a black/brown artificial leather (pyroxylin cloth), a predecessor to vinyl. It was used as the upholstery material in '32-'34 standard open cars, commercial vehicles, and trucks and beyond '34 in the case of the latter two types of vehicles. While dark, it is definitely not black. It had very little texture. Unfortunately, no one presently offers a good match in vinyl to the best of my knowledge.
