I think it used to be possible to get scales (or was it a spring balance) which weighed a Campingaz 907 cylinder and told you how much gas was in it. Either my memory is failing, my Google-fu is up the spout or they no longer exist, but I can't find one on line. Anyone know if they are available? Converting a spring balance wouldn't be hard, but if they already exist ...
