I'm thinking the glass was marked in gallons. Looks like there would be some guesswork in filling to $1.00 or whatever. Maybe they used a magic marker for the dollar marks. Oh wait, magic markers probably didn't exist.Pre WWII and some my have been in use after it, the gas station pumps were hand pumped into a glass tank on top of the pump cabinet. Ask for $1.oo and the attendant pumped the gas up to that mark on the tank. Gravity dispensed it.
