The two specifications have the height 1/4" taller/shorter.
(Parts, or spring sag?)
By studying the construction and design of these, in the few good photos and promo sketches that exist of these, it appears that the center beam of the frame on these hoppers is an open box made of what appears to be two beams that are about double the height of the (easily seen) side sill beams. This is to allow an unobstructed dump shute down the middle. The center frame on these cars is the area that info is seemingly not available on. There are a couple of photos of the K&J hoppers that lived at the Montana Southern (30") RY, that also show the large center beams, but sadly those cars were scrapped a couple of gears ago. I so wish they would have saved 1 and just let it rust! We might never figure these cars out without having one to look at.
in order to figure these out someone might have to scale the two K &J promotional pages and see what is learnable by putting in the known dimensions. That center dump area might still not be revealed very accurately by this method of deduction. Its the worst way to figure these things out, but it might be the only way still available.
Create projects so fantastic they inspire others to undertake even greater projects.
