In reference books The Qaunah Route a Texas Short Line RR by Charles C Britton, Page 48 and The Quanah Route by Don Hofsommer pages 141, 128, 123. If someone could look and tell me what kind of tank car these were and perhaps which HO scale model is close. And what color were these cars? White and Black or Red lettering? Or were they Silver and Black or Red lettering? Any insight, thoughts or advise would be appreciated. Thanks, Tom in GJ
