@breezinup posted:These were not part of any set. They were produced in '74 and '75, with the white-lettered version produced first, and later the black-lettered version. The black-lettered one is scarcer.
You may be thinking of the no. 9417 and the no. 9729. These two cars were only available as part of the Great Plains Express set. The 9729 was in the set from '78-'79. and it was replaced by the 9417 in the second version of the set in 1980. I remember buying the set to get the car, not knowing whether the 9729 or 9417 would be inside (it was the 9417). I picked up the 9729 later. I have all or nearly all these Pacman cars, and run them behind a LionChief Plus CP Rail GP38. Makes a very colorful train.
Fairly certain the 1866 Great Plains Express was only offered in 1978 and 1979, it does not appear in the 1980 catalog. Here are the photos from the 1978 and 1979 catalog.
