Does anyone know what became of ACF's builders photos of early Frisco passenger cars? It would seem that like Pullman and Budd, that ACF surely would have taken builder's photos of equipment that they built just for their records as a matter of course. I know a lot of Pullman stuff is available, and some Budd stuff, but does anyone know what became of ACF's archival material like that? Was it lost in a fire, or simply discarded, or does a museum or library somewhere have their collection? Anyone know?
