Lol, yes, the second picture is from a railway prop, real world scale model, not 3D.

And no, I don't think De Espona based their design on the railway model, I think both were rather based on a real building. Many of the models are based on real buildings, and many of the scale models are actually made from injection moulds made in 3D programs, so there is a possibility that the scale model was made from a 3D model, possibly the De Espona one. I know that De Espona did sell models to scale model companies, but not sure in this instance.
