Another unique feature of this car is the small button/mushroom vents mounted on the upper ends

The '31 CBC included drawing of both. They are virtually the same, with
only a few very minor differences that would be irrelevant to most
modelers. For example, the cast draft arms for one are for a horizontal
coupler yoke (two draft keys,) while the other is suitable for a
vertical yoke (one key.) The single I beam appears to have a slightly
longer splice plate where it is cut  to taper to the bolster on one of
the cars in comparison to the other. But, the carbody and underframe is
the same design.
