I live in the Optimus 111 "epicenter" - Norway. The Norwegian army used these for decades, and as a result there are a lot of them available here, at decent prices. I also think Optimus sold lots of these in the Norwegian sporting goods market. I have a few roarer 111s that I hardly use, but decided to get a 111T whenever a nice and inexpensive one turned up, and here it is: It looks almost like new on the outside, just a few very small spots of worn paint. The case and sticker is plain, civilian 111T Inside is also very nice, little wear and no sign of anyone ever closing the lid on a hot or burning stove The seller was not a stove guy, he had several for sale and I suspect they are from the Norwegian army. To signs of this is that it has securing screws for the outer cap, I think only the Norwegian army ordered burners with screws for the cap, and it has had a "army fettle"; a full maintenance kit + a new tank lid. The o-ring for the plunger was new with fresh grease, the jet, NRV, spindle and packing box was also new. It came with the tank half full of kerosene, so I just fired it. Nice blue flame, not much smell of kerosene Yellow, smelly flames when simmering. Perhaps I had too little pressure in the tank. However, I really do not like burning kerosene, it is always smelly and also produce some sot no matter how efficient the burner is. So, I went against my own advice and emptied the tank and filled it with white gas, Aspen, closely monitoring the pump plunger for any sign of leakage past the NRV. Burning well, blue flame and no smell whatsoever. Perfect simmer With Aspen it would boil 1 litre of cold water in 5 minutes 30 seconds, outside. Not too impressive, but good enough. Tank pressure probably was conservative. I love this stove as it is, the little patina its got I will keep, and it does not need any fettling. But I wanted to give it a good cleaning before further use. The tank and burner cleaned up easily. The case got a quick clean with dishwashing liquid, a smear of carnauba wax and a beer can liner Even the front lid was free of rust and wear Ready for some more decades of use. I can not tell wether this stove was made for the Norwegian army, or if the Army got civilian boxes as spares, or if it is indeed a stove sold to the civilian market that has ended up with an army burner. It does not really matter to me, its a good stove anyway. The only thing I would like to change is the o-ring pump plunger. It works ok, creates enough pressure in the tank, but it has got a sticky, jerky action to it that the stove and everything on the table shake as I pump pressure in the tank. I have tried silicon grease and I have tried oil, it still has this uncomfortable action when used that I don't like. I will substitue a leather cup plunger. Tron
