I believe he was just one of the regional representives in charge of the western zone,so anything special had to go through him,and be billed/recorded accordingly.
A Brass Hat vehicle was one tapped for corporate use first.The reasons for this vary from anything like monitoring quality control,to a public demonstrator,to special favortism.
The zone 36 billing address backs this up as well as the 000 dealer code.
Technically Chevrolet Utah paid for it first,then it was delivered to Merrill Bean Chevrolet,and most likely driven around for a few months by a GM/Chevrolet employee,then later sold to a public consumer.
G R Browns name appears on other similar vehicles paperwork delivered out there as well.
