Well, not a BAD guess, Rich, close but no cigar, so far anyway  I have a diagram of ERIE 97250-97399, a 40 tone double door box with end doors, but the roof drawing doesn’t look like a rectangular panel roof.  Of course, equipment diagram books are not to be taken completely seriously about things like roofs . . . The roof is not identified in what might be called the “agate type.”

I’ll have to see if I have a photo of this series, but I rather doubt it.
