The earlier model had a simpler control key which was at a pronounced downward angle.The later model, the 123R had a more multi-purpose key & a built in cleaning needle & is still made today.I believe the Svea 123 appeared in the 1950's (despite claims of an earlier vintage) although Optimus, Barthel & others were doing very similar models as early as the 1930's. The earlier 123's had the part number inscribed on the flame spreader & filler cap & the model name on the outer windshield. I own and operate, or have operated, or have seen operated just about every kind of stove thats on the market today or has been on the market for the last fifty years. The most common types of fuel include wood, white gas, kerosene, Isobutane, propane, Sterno, and alcohol.
Stove also says Benzoline, Petrol, Essence, Bensin. Thanks Monte Some may find this a little controversial to question the pedigree of the famous Svea 123 but hopefully it'll maybe get some facts to surface about this stove!
Wood cook fires will coat your pots in messy soot and that can get inside your pack if you dont clean them properly before packing.
It takes longer to cook over a campfire since you have to get the fire going, burn enough wood to create a good bed of coals, then wait for the fire to die down some so you can get close enough to the fire to start cooking.
I would be interested to know from anybody of any dated references for this model & would certainly like to know the model of the 1920's stove you refer to.
