As our research continues on this car it appears that this Z/28 was bought by Phillips Petroleum Marking Department. According to the NCRS paperwork the purchasing dealer was Phillips Petroleum in Oklahoma City, OK. Phillips Petroleum's corporate headquarters was and still is in Bartlesville, OK, but their marketing department was and remains in Oklahoma City, OK. So, as our research continues it is safe to say lineage of this Z/28 begins at Phillips Petroleum's Marketing Department.
