camping stove (Dunfermline)

The previous owner of our property has left a slightly rusty fairly full camping gas canister (for a little stove) in our shed... don't really want the gas sitting around and the only way I can think to safely dispose of it is by screwing into a stove to let the gas disperse. Feels like such a waste to buy a stove for the sake of it! Does anyone have one I could borrow? Thank you
