Conversely, the Western Pacific GP-7 appears to have received gray paint meant for the O&W diesels.
Therefore, I wonder if Lionel will produce corrected silver painted replacement shells for their Lionchief Plus Western Pacific GP-7 ?
With a keen eye, you can see that these paint mix-ups sometimes occur in pairs. For example, the conventional classics Virginian rectifier set got colors swapped. The Timken boxcar's yellow was on the engine, and the engine's yellow made it on the Timken boxcar.
