Very cool. Was it a baseball cap or a western hat? Did it have the same crest? Check out this video with Dodge commericals from 1967 at the 2:40, 17:31 and 26:40 minute marks.
Hey, I like your patches. The shirt in my avatar was my dad's. Maybe you can make out the patch on it. He was service manager from '65-74. Have his pentastar fabric service manager shirt too from the early 70's. Super cool.
