A vintage kerosene-powered radiator heater (such as a Paraffin/Kerosene Sump Heater or Desmo Radilamp), likely dating back to the 1930s or 1940s. Original purpose: These lamps/heaters were used by drivers who would hang or place them beneath a vehicle's engine or radiator on cold winter nights to prevent the water or oil from freezing—a practice common before the advent of modern antifreeze fluids. Construction: Features a bottom reservoir for the fuel (kerosene), an internal wick, and a metal mesh top designed to dissipate heat and prevent flare-ups, along with a dedicated hanging hook.
