A few more thoughts:
Last, Andy I don't think one should have to count the boards on these SS cars. The MCB/ARA recommended practice called for 5.25" square-edge T&G on all "outside framed" cars. So a 9-0 IL car should have about 20 boards, and a 10-0 car about 23. I zipped through about a dozen example photos for various roads, and I couldn't find any exceptions.
I have done dozens of scale drawings for mid-century freight cars years ago, and all of them had no readily available drawings to assist me. Counting boards was essential for an accurate drawing. Not all cars, I discovered, had the same board dimensions. Some GN cars had different cars from the same class series with thin board samples and broad board samples. I found cars which had different board sizes on the same car. So to me, counting boards gave me 100% accuracy for at least the one car pictured! I guess what I am trying to say is please understand that not all cars were built with same size sheathings.
All of this talk is making me want to resume pattern making, a very fun part of this hobby.
