I'd have to say hands down it's this. I Picked it up off of fleabay about 8 years ago. It's called a Radius No.15, 100% complete not too bad for a 1930s stove! It even has the original top ring which is viewable behind the stove in the picture below.
A small bit of cleaning was required, replacement of the NRV Non-retun valve puck (the piston kept backing out, loosing pressure, etc.) and a few gaskets as well as a proper inspection. We don't want to loose our eyebrows!
This stove has amazing stampings all over it. In the picture of the buner head below, you can read MADE IN SWEDEN
around the shootingstar trademark. Sole Makers of the Genuine "RADIUS" Apparatus
is written in ten languages that are around the tank/fount; Swedish, English, German, French, Spanish, Russian, 3 variations of Sanskrit & Arabic... Even a nothing trip is turned into an adventure using it!
My other stove (I carry 2 stoves) is the old Multi-fuel 1st generation Optimus-Burton Nova "Made in Sweden" with the Cejn connectors - later models were crap and dangerous apparently, so if you want a GOOD one, read this http://adventuresinstoving.blogspot....imus-nova.html
Mine has been pretty good most of the time. Always carry a rebuild kit (any stove). I've more than once had to do field repairs.
