I've looked for more information about this PROSIT stove at Google website. It returned me only a picture. Searching there, I find a japanese 2WW collector who has one like mine. Seller tells me the stove was in Iran, and he carried it to France with a plenty full fuel tank! And I got it, still full of fuel, two days ago. It seems a Primus 71 or Optimus 80 clone. There is spring for hold frontal cover. There are two jet prickers and extra jet in a kraft paper bag. Lets attempt the Tea test! First priming with meths. Light.... (a quite bit noise) If someone knows where this stove was made, I'd appreciate the owners of the forum move the post to the right place.
