This is a great thread - and a great observation about the position brake cylinders. Working on my Tiffany refrigerator car project led me here, and studying the images of these cars, they seem to have been set up similarly - with the brake cylinder pointing away from the brake wheel, and on the other side of the center sills.
Studying the plans that come with the Grandt line New York (C&S) air brake kit, I realized that there is a simple modification to the brake rod set up that moves the brake wheel to the opposite end of the car and puts on the other side of the center sills, as shown in these pictures. As shown in the plans, the A end live lever is retained on one end by a static rod, which bolted to the needle beam. Having recently completed a passenger car with full brake rigging, it occurred to me that if this rod is connected to the brake wheel, as it would be on a passenger car, it will move the brake wheel to the opposite end of the car and place it on the other side of the center sills, as the images in this thread show.
The other interesting thing in these images is how low the brake cylinders seem to sit on these earlier cars - it appears as if the mounting straps were put on blocking so the brake rods would clear the needle beams, which would make for an easier retrofit. With these two truss rod cars (and in the case of the 27 foot UP cars, no truss rod cars) that solution makes sense, as there are no inner truss rods to get in the way.
I don't know for certain if any of this is right, but is certainly plausible.
