I increasingly suspect that we're looking at a film photography artifact (color shift) in that one photo. It happens.

Yep. Look at the way the body color is rendered in the two photos. In the original post 3 car photo, the cars look black. In the second, there's a hint of green, but the look is more Pennsy Dark Green Locomotive Enamel than SP Dark Olive Green. So either the paint shop didn't follow the specified color scheme *at all*, or something is off in the color rendition in these photos.  It seems to me that deficiency in yellow could cause imitation gold and olive green to shift toward orange and black.
