Have a new Primus 71 - this one with a slightly different twist. This stove has the stamp "AK" on the bottom of the fount which makes it a 1946 version. What attracted my attention was that it had a different (unusual?) burner head assembly. See that little lever... Here is a picture of the inside... And here are the components... It looks like it was designed to provide further protection from the wind. Anyway, here she is after a trip to the spa... And a flame shot - just like any young lady who has just been to the spa, she is a little flirtatious and not quite ready to settle down - thus the yellow tips to the flame! Would one of you good souls tell me a little more about this burner head - what was it designed to do? Was it standard for the 71 of this era or was it an option? How many years was it produced ? This is the first one I have seen in my short tenure as a "stovie".
Sweet stove! And great work on it. Check out this link! Link It is for different gasoline mixes, to adjust air/fuel mix. Remember at this time still stoves could/did burn what cars burned. Jeff
Hi Fuelish ! I have one also, dated 1938, with the same feature. I read that the common use of alcohol-petrol blend (like Cleveland Discol) explains the need of reducing the supply of air (as alcohol needs less oxygen for a proper combustion). Two interesting threads for references : - Primus 71 Edelweiss 1955 - Primus 71 - 1939
I have a similar adjustable burner bell for the M-1942 US military stove. I admit I found no good use for it, although I did not try it in strong wind. Yonadav
Sounds as though this type of bell was quite common for a number of years. The stove makes a nice addition to my collection, though, and it puts up an intense flame when opened up for sure. Thanks all for the links and background, everyone.
