I know just about everybody that is serious about stoves will have an Optimus 111 and I have wanted one for a while. So here we have it, not NOS but not far off it. Has the Optimus Sweden marking on the roarer burner head and Sweden Sweden on the flame ring. Also, it has an embossed lid with the large globe, cookie cutter valve knob, steel wind guard and slotted type fuel cap. So from what I am reading on this forum most likely mid 1960,s. All it needed was a new seal in the fuel cap and away she went with no problems. I see why people enthuse over these stoves, they really are great pieces of Swedish design and they run nice and hot, should be able to boil up a couple of litres very fast. I am glad it had been fired previously as it removes any question about firing it up and enjoying the roar! And it's away roaring!
Wow, so that’s what it looks like when it was new. Yeah..mine looks like it IS 65 years old compared to yours but I love the patina. Great find you got there, word of warning these 111’s have a tendency to multiply.
The paperwork is the original operating instructions and also a pamphlet produced by the New Zealand Mountain Safety Council Inc. explaining which fuels you should use for the stove and how not to confuse kerosene with gasoline type fuels including naptha and alcohol.
Great find, love the condition, always good finding them like that and not much fettling required to get them going.
It looks like a 64-66 one, according to @OMC 's research listings, so would be kero only. Similar to the one I have. Tim
Yes, Kerosene only. Which suits me just fine as the cheapest naptha fuel (we have a product called Shellite here in New Zealand) is now more than twice the price of Kerosene.
You can use gas in a 111, just like a 111B. But, the difference is that you cannot properly vaporize kerosene in 111B. That said, I do not use 111B, abd I do not use gas in 111. I do not trust the valve systems.
This is a great stove, and I am pleased you found one in NZ. I have found that kerosene burns hotter than Shellite or Fuelite.
Yes you are right about Kero stoves being hotter. I have a Coleman 4m twin burner which is a naptha stove and it is not as hot. I also have a few single burner brass stoves which are pretty hot but I have found that the roarer burners are definitely hotter than the silent burners.
