I've mentioned the Freeport Milk Products car on this forum before and it is definitely one of my sentimental oddities - the base car is an American Flyer NYC reefer (example on left) which was hand painted and lettered. It looks like the Flyer car was new when it was over painted. The Freeport graphics are correct for the real car and, given the probable time of the hand painting, I think the colors for the hand painted car are prototypical as well.
