The top photo is another of my favorites from Col. Chet McCoid. It was recorded either very early or late in the day when the low light angle provided excellent and even coverage of the surface details. This car had not been repainted since it was built, so it has a dozen years of service reflected on its surface. Of note are the rather low crossbearers of the Duryea Cushion underframe and the XLT (or Tatum) slack adjuster, the rectangular appendage to the right of the AB brake reservoirs. John Tatum was a B&O employee and prolific inventor with many patents for railroad-related appliances, including this slack adjusting device. There is an article about the adjusters in Volume 44 of The B&O Modeler, including how to model these devices that were common to many B&O freight cars.
