Just spoken to my brother and he said that it was Bialaddin lamps that he bought.
The civvi version is called Vapalux.
I've tried to find his link and I think is sounds like base-camp.co.uk
I know of another make, Veritas, too. We used them in the scouts a looooong time ago
No idea which is best, I've used them all and found no problems if you pay attention when setting them up, and clean them thoroughly occasionally.
Good kit, a really good light and warm too
I've got two in need of some work in the shed (been there about ten years or so
) might be time to do something about the sorry state of them.
atb,
