This is the middle type of Companion kero burning brassie. That means it has Companion - Companion on the sides of the air screw and the larger logo. It followed the earlier Companion stoves that still had the SVEA in the logo. The Models 1 and 2 both have the stamped words hatched in. Type 3 were later and did not. This well beaten stove gave me hel getting it right but she is finally running well. Interestingly a brass gauze filter was found inside at the top of the fuel pickup tube and it was fairly well blocked. The burner tubes were a mess too start with and got soaked in vinegar and 150PSI clean out. The NRV was letting liquid back into the pump housing and was replaced. Great to get an old beat up unit running well. IT LIVES. I have left most of the patina as is. The jet was too large and gave too much yellow. Unusual detached flame. Found crud in the replacement outer burner cap. Burner cap cleaned and finally a nice flame. As it arrived.
