This is a single-mantle lantern, made in the USA in March 1990. The generator is slightly thicker to accommodate unleaded gasoline. The pump cup (made of rubber) has been replaced with a new one. For an older single-mantle lantern with an aluminum pump, I think the condition is quite good. The original case is included. (The case was manufactured in March 1990, the same as the lantern.) Ignition has been confirmed.
