True, but the emblem appeared at least as early as 1955, well
before those 60-foot cars appeared--and in any case the latter period
is off the end of the permitted period of the list <g>.
DF was a trademark of General American which I believe had the original patent for belt rails with interlocking bars across the car. Evans also was involved - don't recall its relationship with GA. The generic term used by the railroads, which you will see in the ORER and car service directives, is "load-protective device". That term also applied to the vertical inside door type devices, pne of which was the tradmark "Compartmentizer".
