@Toby Garner WOW! I've never seen a Coleman 400-499 (Brown one) spewing pure blue licks of flame into the stratosphere! Many others as well? Is your house situated on the steps of Hades or are you burning nitro-methane in your highly modified "Dragster-Stoves"? Seriously, it seems to me like the absolute peak of knowledge relating to combustion! Very impressive! Congratulations! Golf-Clap! Golf-Clap! Golf-Clap!
Here is a quickie of a Coleman S.S. Fyrestorm. Canister about 1/4 full. NO APPRECIABLE PHOTOGRAPHY SKILLS TO SPEAK OF! Nothing I ever felt inadequate about until I joined CCS.
@Boron40 the early 400 stoves (and their close relatives with the separate control lever) are Coleman's best single burners pound for pound in my opinion. They simmer with the best 502's and stomp the 500 in max BTU output regardless of the advertised outputs. It's a shame Coleman did not support them for longer and the obsolete generators have skyrocketed in value...
WARNING: Propane involved. Right hand burner. This is a Primus 2062 running on LPG. It works a lot better when the wasp mud is cleaned out of the pipes! When I’ve cleaned it up a bit more I will post it in the Reference Gallery. Tony
Here is my latest Høvik Verk Standard 36. This one has a Radius 5/37 burner with a bigger cap (as shown in the 1920 catalogue) . No under burn with this one
Don’t worry about the colour of the flame: that’s just 110 - 120 year old brass coming to terms with being used again. Cheers Tony
@gnome Great stuff ! I have a Burmos 51 on the workbench at the moment . I hope I get as good a result
