Speaking of which, has anyone seen a good roof shot of C&O 4500-4999? Larry Smith said they had Murphy roofs, not Vikings, but I've never seen proof either way.
My copy of C&O's 1960 Freight Car Diagrams notes that these cars had "Hutchins Dry Lading 15 Ga." roofs, Youngstown doors, Dreadnaught ends, Ajax brake wheel and wood running board.
