It's a Mercury. 1947. There were two used in the show altogether. One was for sale in Colorado in 1998 or so near Fort Collins, by an outfit called Classical Gas Station, if I remember right. They had the studio paperwork and documentation to go with the truck. They were pretty proud of the truck then, as they were wanting $15K or so. Saw the truck myself. I was there looking for a COE Dodge or Chvy to build a hauler from, and looked at the Merc, among other things.
