Høvik Verk had three versions of their 1 litre domestic stove. No:31 with roarer burner, No:37 with silent burner and the No:36 with a special silent burner. Appart from the burner the stoves were identical. No numbers on the tank. Her are some photos of the No:36.
This system where the flames are going downwards could be the solution of silent burners on the more modern roares as Optimus Nova etc. I tried to talk to Optimus, but noe they have new owners, and Ill guess those who lost their jobs are probably not that entusiastic any nore. dsk
Thats a good looking stove you got there, and a really nice flame The burner used on the Hövik is the same modell as my Radius No 5 is having. For more pictures se my Weekend fetteling
