These were used by both the oil jobbers and the local city or county inspectors. The inspectors used to come out to my Shell station once a year (maybe even twice a year), check each pump, and charge me $5.00 per pump for doing it.
The were used so much, I doubt any of them still have the original paint on them.
Don't remember Shell ever coming out to check the pumps.
