I know John, totally out of character, but at least it comes with pics, just a few below showing the old petrol cooker which was only for camping grade fuel, low grade UK petrol, says not to use USA or Canadian fuel ? The Hexi cooker and the latest ( none issue ) yet to test it but seen them in action and they are quick,
The Hexi cooker shows the base that the metal cup for the 58 Patt water bottle fits, the last pic shows the more modern version of gas cooker, folds away into a 3" x 2" x 1.5" box.
