[Phys-L] Re: Antique Gas Pump Question



You filled the cylinder to the number of gallons you wanted to
purchase, then placed the hose nozzle into the gas tank opening. ...

The next big advance came when they figured out a way to accommodate
those who didn't know in advance how many gallons they wanted to
purchase and anticipated the question:

why is the ten on the bottom?
