Got this one from Denmark...as all other simplex/komfur stoves. Must have been a popular export stove... This one is a survivour found broken i 4 places in the cast iron trivet and a broken leg...Took ages to rebraze with quite expensive silver solder... Comvered to run on apen ultraclean petrol as i use it inside the house - it has almost no odour compared to kero or even alcohol! External nrv...not sure how it works (only used to regular screw in type) but it does not leak after a pip change.
Beautiful stove; great restoration! Do you control the flame with the black knob, or by venting at the tank? I would be reluctant to do the latter while burning petrol (especially in the house). ....Arch
