This vintage Parasene kerosene blowtorch is a brass soldering tool manufactured in England, featuring a blue flame burner. These antique, pressurized tools use methylated spirits for preheating to turn kerosene into gas and are popular for industrial decor, display, or restoration due to their sturdy brass construction. This unit needs a good cleaning and polishing. The last picture is one of a slightly different model after it had been cleaned up for display.
