I am working on a Southern Car & Foundry 6 radial course tank car with decals for a GATX tank car.  In looking for a photo I could only fine two photos in Hile’s UTLX tank car book.  From my hunt I believe these were not a common tank car.
 Asking if anyone can direct me to a photo of a 6 radial course tank car lettered for GATX.
Thanks for your help in advance.
