An interesting bit from the MR forum:
There was a Carstens reefer. A full size one. Maybe more than one.
Anyway, there's a photo on this site (about 3/4 page down)
If we're flinging the word "cute" around, it would certainly stick to this car.
I figure there's only one ice bunker, not one on each end. And I also figure the door on the other side lines up with the one on this side.
