Well, second attempt, my first post disappeared completely. When I joined this forum a few weeks ago, I couldn’t think there were so many beautiful stoves. I already did have some stoves, mostly hiking stoves, Trangia 25 & 27, Svea 123, Optimus Nova+, Phoebus 625 ect. But then I noticed the household stoves and I knew, a purchase would follow. I searched the forum for models, made a wish list, and started with the hunt. The Primus N°2 was on the list and I was luckily to find this one in good condition. I drove a 260 km to get this one. The seller told they were stocked in the underground shelters during the cold war for a citizen protection program. The seller bought it from a Army surplus store and he never lit it, only cleaned it. I noticed some of the text “Primus N°2”, at the bottom is faded, perhaps during the cleaning? The stem is marked 201957. I’m not familiar with fettling these stoves, but I want to learn. When I want to pressure up the stove, the pressure is building up in the tube, so I guess there is something wrong with the NRV, blocked or something? I already poured some kerosene in the tube, but that didn’t helped. So I’m going to remove the NRV when I have the tools, hoping I can get it to work.
