Tufts reports the 2H342 contents as identical to the K5437T, no additions or substitutions. I have the Sears Wish Book but not the MW. In theory if MW sold it , the set should be in the Tufts book.
I own one of the uncataloged sets not in the Tufts book. It was made for Kaufmanns Department store in 1950 in very small quantity. The set is numbered 4611A, but has a 632 hopper in place of a 629 cattle car and a 577 illuminated whistle billboard w/o box in the set box. The 322AC is mid 1950 production. I know the provenance because I am the original owner. I am sure there a few more things like this yet to be discovered.
