Greetings,

In a collection of photos taken at the recent Naperville prototype modelers
meeting is this photo of Steffan Ehnbom's fine model...

The roof on this model surprised me, as I've read that GN boxcars in the
15000-15549 series had roofs with rectangular panels and these roofs were
painted (or covered with car cement) black. Are these published sources
incorrect and if so, what would be the correct roof reference/name?

As background, these cars were originally Erie-Lackawanna 78500 to 78999 and
79000 to 79199.

Thanks,
