As pictured above, these models are available with or without roofwalks. Additionally, Athearn refers to some of these models as "late" and others as "early". I'm not sure if that has to do with paint schemes or what.
Lightly weathered versions are also available -
Here's what Athearn has to say about them -
In the 1960's, Ford Motor Company, Pullman Standard and Santa Fe pooled their resources to develop a standard boxcar to meet the transportation needs of automobile manufacturers in the United States. Delivered in 1965, the Pullman Standard auto parts boxcar is the most prolific example of this type of freight car. It ultimately changed the face of automobile manufacturing and rail transportation.
