> PS I have not checked but might the new Tangent hoppers be a starting point for a model of these?
Tangent's 3-bay hopper is a Pullman 15-panel PS-3, 2700cf if memory serves. L&N owned a LOT. Southern, I don't think so.
These clay hoppers were rebuilt from 9-panel 3-bays, a post-WW2 AAR standard design mostly associated with ACF. I don't recall who built the Southern's. (It's in the diagram book, I'm sure.) Atlas makes a basic model of this car in their Trainman line. The old MDC rib-side 3-bay is also this design. Neither are going to be confused for a Tangent.
Ike might have been thinking of the recent Arrowhead Models coal hopper, which is a 12-panel 3-bay. The original NS got some of these, and of course these went to the Southern. I wonder why NS bought those?
