This is a vintage-style blow torch that operates with kerosene oil.
It's made of heavy brass, giving it a shiny finish and high resale value.
It's used in various applications, including handicrafts, plumbing, goldsmith work, and for heating purposes in homes and industries.
To operate, you pump it to pressurize the kerosene, which then vaporizes and produces a powerful flame when ignited.
When filling, leave some space in the tank for optimal air pressure.
