Flamethrower

[Convair880]

When you take an o2/air tank from a flamethrower while wearing a gas mask you get an O2 quick-button at the top of the screen. But adding the tank to the flamethrower does not delete the button.

After some testing, it would seem the HUD icon is tracked separately for every tank. Removing the same one and attaching it again doesn't result in another icon, but using a different tank does.
