interesting , a hand made piece.. so very limited numbers..
The Borde Benzin Brenner was created in 1956 by the Swiss inventor Joseph Borde and was later transferred over to Norbert Baader who is still making them by hand. Only a couple hundred are made a year and can only be easily found in some European specialty shops, Japan and on Ebay

Part of what makes a stove bigger is the pot supports..
there are simple light Alcohol burning stoves of Titanium.. , really simple because of the fuel used.
MSR whisperlight is thoroughly tested, spare parts available around the globe.
and if you leave the pump in the fuel bottle, quite compact to pack..
I use their midsized bottle, it goes in that under the frame water bottle cage.
and got a sewn cover made for the pump, left in the bottle.
