Not sure what the N means. This cute little baby was given to me by a guy driving an old Invicta car he was showing at a small local steam rally. He said it had been his fathers. I think it is probably 1950s but the Scandinavian brotherhood will know better. Neat lantern with a bayonet fixing for the hood and a lock built into the pump handle. Runs OK too. I have it working here with a Coleman #20 mantle which is really a 150 cp and works quite well in these small lanterns.
Dating these is not very easy, though I have seen a picture in a brochure from 1949 where the lantern has 100N on the tank. From this you can assume that the N suffix is from at least 1949. The 100 model dissapeared from the range in 1957 when there was a big change in all the models. What the N means is a mystery.
N for Normalljus? That's the Swedish equivalence for CP. Nah, it's a long shot, and probably a bit to far-fetched. That would not be consistent to how Optimus has named their other lanterns either.
Somewhere amongst the pile yes. I might even know where to start looking. I know it doesn't work too well. Runs OK but with yellow halo and poor light. Probably wants a generator clean out. ::Neil::
Could you supply me with a few pictures of the inner roof/top complete with mixing tube and flame spreader?
Whilst I had it on the bench I cleaned the generator and jet. It now runs very bright. I didn't measure the light but it had to be near enough the 100cp they were rated at. ::Neil::
