This 2003 Coleman Model 442-725 ‘Exponent’ Feather stove is a beauty. She can hold pressure for several months at a time, if required, and lights instantly on Shellite (denatured alcohol). I have never used unleaded in it and don't intend to either! Suffers slightly in a breeze but overall is fairly stable on most surfaces and cooks quickly with good flame control. I don’t like labels and removed them all. The unit is free from rust and I obtained it new on 23 December 2003. I have all labels and instructions. There is also a matching Coleman 'Exponent' lantern too.
