That looks much better. :)
Nice to see another one of these. It has the original vapouriser and spirit cup too (mine was changed to 119 parts). Do you mind if I ask where...
The Px style conversions have both a larger jet and a restricted airflow. For a 300cp lamp like this the jet should be 0.3 mm. A 0.35 mm jet...
I was expecting that they would have to be restricted, as is normally done with a Px style lantern (or Primus).
Just a bit of advice. Do not use a screwdriver in the slot in the valve body. This can break off one of the sides. I always use an old drill chuck...
Interesting mantle shape and size (too small), but otherwise it looks like a good flame. Looks like a mid to late 1940s variant.
Did you do anything with the air intakes?
The seat in the filler cap is different depending on the type of air release screw fitted. Originally it was a conical end on the screw that did...
That is a very nice example and great to see. As Tony mentions, it does tend to confirm the assumption that the 200 is the model name of the...
Probably from the last few years before 1957.
Isn't it 225?
I agree with Collin. Probably designed to fit into an outdoor housing. Someone has probably electrified the housing and had this left over.
The Optimus 100N was made in Sweden.
@presscall The fuel consumption is noticeably higher with the alcohol version. There is still enough for a good night of burning, but it needs to...
That is a nice find and it looks to be original and complete, even the glass. It is the first variation of the 300 with the one piece vapouriser,...
@Terry Crow Thanks for that. That is the parts list for the final variation of the 930 (ca. 1980s) which I don't have. All parts lists prior to...
@Terry Crow Just back from holidays and catching up on the forum. I have never heard of an aluminium washer on an Optimus 930. The parts lists I...
With the one piece vapouriser and access to the cleaning needle from the bottom, it is early 1930s. Possible 1931 or 1932.
Separate names with a comma.
