That was a lucky find! I had one of these many years ago, same model with the dual controls. Fantastic cooking stove for backpacking. On the heavy side but really adjustable flame and quiet. I would buy another if they still made them. I watch ebay but they always go for too much money:)
Enjoy the stove, definately a keeper!
