Extremely cool pictures there.
I know nothing about plywood in the auto industry, and the only observation I have is the cutout size around the rear wheel well produces a very narrow piece on the deck. I'd be leaning towards that piece being solid wood material for strength on the exposed edge. Then one could argue if the outsides are solid why use plywood in the middle? Don't know just saying from my perspective. At any rate, I love seeing early assembly line pictures. We need to find an 80 year old GM truck assembly line worker that knows how to get out of the rocking chair and get online here.
