Craig I think the woodgrain veneer is just a laminate, probably from one of the big 3 back then, Formica, Wilson Art or Pionite if memory serves me right. If so and if the factory could look it up there might still be some available. (I am not sure Pionite still exists as a company).
Knowing the manufacturer of many of the components would sure be a great help in some cases. I wonder if the AS company would research if asked?
BTW you mention "a next owner" . Are you planning on getting out? I'd hate to see you leave us.
