Once again I seem to have too much time on my hands. I was perusing a set of decals with my loupe and spotted tack board lettering "For Grain Loading". Now the question begs were these prototype cars and any known numbers? Where were they used (from where to where?) and why were they stenciled/assigned? I guess that would answer the why. Also what was the earliest year for stencilling/assignments? Did they just handle grain or were they used for beans as well. Questions, questions. Thank you. Paul.
