Owning a gas pump years was like, what brand of gas are we selling now. Owners of gas stations purchased their gasoline from a local distributers. If the distributer owned gasoline stations, the company he was buying gasoline from was on the big sign out front. So over the years things changed, this year if you owned your own station, the supplier of your gasoline signs were on your pump and the big sign. You could change suppliers, buy your gasoline from another supplier, again the pumps changed color as did the sign out front. Same with the local supplier, if he changed suppliers, he showed up with new signs and maybe an offer to repaint your pumps.
Then.....if you decided to buy new pumps, your old pumps were generally sold to a rebuilder of pumps, some of them would even repaint the old pumps. If your pump went to the seller of the new pump he would rebuild the old pump and sell it to almost anyone who could not afford to purchase a new pump.
So....now why do pumps have six or eight different layers of oil companies on them? Just go back to the beginning above.
Again, So.....what should you do. Did your uncle have an Standard station years ago? Did you buy your first gasoline from a Gulf station? Did you....well you get the idea, have fun with your pump, it doesn't matter what you restore it to. No one will ever care, if you do a good job, all they will ever say is "that is a great looking pump."
