Thanks for posting the additional pictures!

Looking in the restoration book, the paint scheme jives with Pure Pep from 1955-61 or Pure Firebird from 61-70. Or, it could have last been Union 76 Regular from 70 to the 80s, after the buyout. The red underneath could be the pump's factory paint, or from a previous branding.

Looks like someone stole it's friend... I bet there was a Pure Premium pump next to it.

Keep up the great pictures, guys!
