I've been having a bit of an email banter with Richard over at Einzel Kocher. Along with his various stoves he's also selling 100ml and 200ml fuel bottles - ideal as I was looking for a UK supplier of these sizes. The 100ml is ideal for day trips - I get three brews out of one of these when used with a Gnome. The 200ml is made from aluminium and looks just like a mini sigg bottle, and both came with flip and screw caps.
It's good to see someone giving it a go in the outdoor gear cottage industry, so pop along have browse and make a purchase. Go on Darren he's bound to have a stove that you must have for your collection :)
