The Lionel Trains Truck Trailer Car No. 6810 was produced on a RED flat car mold in 1958. As with almost all of these cars that have AAR trucks, the number "6810" is to the left of the "LIONEL" inscription on the side. This flat car has operating disc couplers. It came with a Type 8 WHITE trailer that has a BLACK background painted plate that was lettered "COOPER JARRETT INC" on a COPPER colored arrow (Variation 4). There are two variations of this flat car:
Variation A: The flat car chassis uses mold No. 6511-2.
Variation B: The flat car chassis uses mold No. 6424-11.
