Camping stove, gas and headtorches (Halton LA2)

This suits was rescued off the fells from an abandoned fly camp. The torches were submerged in a bog, so I've no idea if they work or not, but would need new batteries to test. They've dried out fully so probably good to give them a try.
I tried the stove but struggled to get it to light - someone worth more inclination may succeed?
The gas is about half full.
