Old twin burner camping stove, gas bottle and a pan (Marchmont EH9)

This is an absolutely ancient (1970s?) "Tilley Twosome" twin-burner camping gaz stove, with what I think is called a "904" size camping gaz bottle. Seems to work well enough, although I'm not sure how much gas is left in the bottle. Can chuck in a rather worn non-stick pan too if wanted. For collecting from Marchmont; is quite heavy with the bottle.
