Appologies for pincing your pic.
I have leant my gas bottle to the shooting club but we only use it on friday nights, but the other clubs that go down are nicking our gas and arent paying for it.
What im after is, does anyone have a blue gas bottle like the one in the background pic. If so could you please measure the top part of the bottle where the gas valve is. I want to know the internal diamater of the sleve that also acts as the carry handle and the height of it from the top of the bottle to the top of the sleve, Basicaly im going to insert a tube over the valve and lock in into place using a bar throught the handle so the cheeky beggars cant use it.
