I've a Campingaz Butane cylinder (2.72kg) if anyone wants it. It was given to me by a friend recently but I've decided to go for the bistro type cooker. I've not really got the space to store it so it's free to anyone who wants to take it. It's a bit on the shabby side but it's full, with the red safety seal on top. I'm coming to the Peaks camp and can bring it with me.
