I have a Macy set from 1940, #7135WC. It includes a Gunmetal 249 loco with gunmetal diecast coal tender and freights include a dark orange 2656 stock car. I don't have, but believe there is a 1940 uncataloged set with a 229 that includes the 813 tuscan stock car.
I have always wondered if there is a Lionel set that has a refrigerator car in it.
