Briefly, I have acquired a Tilley Trojan mk 2 double ring stove. It currently has a black hose attached which is 8mm and dated 1993 so it needs replacing. I want to use it with my 4.5kg Calor bottle, and also a Campingaz bottle (which are both Butane I understand - and I have the correct regulator for each bottle). The stove has a sticker on it stating it is suitable for Gas Butane or Propane and then says Butane 11" W.G. (28mbar) Propane 14" W.G. (37 mbar).
What colour hose do I need - black or orange? As this is 2nd hand I don't want to assume that the black hose is correct, but no one seems to be able to tell me which hose I need, I don't want to put my family at risk with the wrong hose!
