The Taykit pocket stove by Taykit Inc in Stryker, Ohio, USA is a very compact coil stove that burns white gas. It packs up remarkably small. I have read that some versions of this stove had a case made of stainless steel, or monel alloy. This one came with quite a bit of corrosion, so I think it may be chrome plated steel. The stove itself is brass. This stove has been creatively designed to combine uses of the different components. The filler cap has a wire needle for cleaning the fuel jet in the coil. The funnel-stopper is as described, it's a stopper for the jet during storage, and a funnel for fueling the stove. The rubber stopper surrounding the funnel was brittle and useless when I got it so I replaced it with some 1/2" silicone tubing. It assembles like Lego by simply pushing the pieces together. The dimple in the top of the fuel tank acts as a reservoir for priming. The instructions say to warm the tank with your hands until a few drops of fuel come out the jet, and then to light that. I opted to use methyl hydrate, as I didn't want a sooty mess on the QA bench at work. After a few seconds of preheating, the fuel vapor works it's way round the coil and it lights automatically. Starting with a small blue flame, but leveling off with a powerful concentrated flame. I've cooked with this stove a few times and it definitely makes a hot spot. Boiling water is about the only cooking I would ever want to do with it. I admire and appreciate the ingenuity that went into designing such a compact and simple stove that makes such good use of its parts, but I don't know when I would ever choose to use it. If I wanted a compact white gas stove, I would much sooner reach for an 8R. If I really needed something packable to boil water, I would probably abandon this hobby and go with a modern isobutane stove. I am sure it was the pocket rocket of its day, and it endures as a stylish relic of Americana. It certainly looks cool boiling an Erlenmeyer flask. Anders
