Early AAR 50 ton flats (Union Pacific?) were built with wood stringers. Perhaps some 70 ton cars were also built that way.
I vaguely recall (perhaps incorrectly) that Byron Rose's AAR 50 ton resin flats had the wood stringers. But I could just be
confused. :-

I was heading there Jack but after seeing this photo I’m not sure. This is a Lot 721-F car. The end flanges seem to sit completely below the deck already, so why go lower in the middle? Note the use of wooden stringers (to conserve steel during the war?).
