I seem to remember that, during wwII, the guys at some eastern US air

vending machine makers and operators of the day.

Does anyone remember more details?

Dunno 'bout that, but I remember a kid in college that used aviation snips
to change pennies into dimes for the cigarette machine.

Until the ATF agents came snooping around...
