Did you know it was based on an Australian design. Its popularity increased in World War II when the company started producing this soley for the US army. It was prefered bacuse the design allowed it to be windproof and face harsh weather. I saw this one at a friends place, who was crazy about this. It has quite a cult following it, and the number of designs are endless. There is a museum in Bradford, which keeps rare ones including I guess the ones initially made of brass.
I kept a timer again for this one and exposed it for few seconds and was blowing away the flame in other directions to get a small burst feel, while it was exposed. I also used photoshop a bit to give it more depth of field, my first try at doing so for a photograph. Nothing great, but had to put this one up purely on the basis of popularity.
