Good looking truck, Great condition for it's age. Looking inside the rear of the truck there is a large Jet Vessel for filtering water. Indicates an intended use for Jet A Fuel. But other distillates work fine (ie: farm use)
Typical farm service trucks had multi compartment tanks. Wonder why "Flamable" is miss-spelled? Looking at all my old tanker photos they all spell it with 2 M's. Trucks from that Era did not have placards, just Flammable or Inflammable on them.
