This is one of two Sirram Volcano kettles that I own. The set consists of the conical water container with stopper, the kettle with stopper and the firebase. When in use it is lifted on and off the firebase by using both the swinging top handle and the small bottom handle. Using the top handle only results in singed fingers (but you only do it once!). For travel, the conical water container fits up inside the kettle and then the firebase is inverted and inserted into the base of the kettle. The base is held in place by two 'lugs'. Both the water container and kettle each hold 1.5 litres of water. So carrying a full set gives you 3 litres of water. The set without water weighs 1.11kg or 2lb 7.3oz. The firebase is made of steel whilst the kettle and water container are aluminium. The firebase for my other set is partly burnt through but this one is solid. I use the set quite frequently so to save wear on the firebase I bought a stainless steel pot at a car boot sale (swap meet) for 50 UK pence (about 75c) and cut a section out with a disc cutter. I understand that there was also an optional water carrier that looks very similar to and is the same size as the kettle but has just the top handle and a stopper in the top. Below is the only picture I have ever seen of one. I would love to get hold of one of the original copper and brass versions shown below but no luck so far!
