Aluminum REA Baggage Car #2540 Help

[traindaddy2]

Hi!  I have an "O" gauge extruded aluminum baggage car marked Railway Express Agency #2540. It has a gray top and gray shaded sides. The silver trucks are marked WILLIAMS.  My question: Would anyone know what railroad line name plate was originally on this car and when it was made? I've tried to match it to pictures of Williams aluminum baggage cars but none of the ones that I've seen have the gray tops or sides.

Many thanks.

dad-

I suggest that you post this question on the Williams board. But please limit your posts to only one board for any given topic. Finding the same questions in more than one place is confusing and wastes time.
