Calor Gas

In the days before the attack Masood also searched for Birmingham Calor Gas Centre and Mr Brown accepted it was "at least possible" he had planned to use gas as a weapon.

Customers have vented their anger after a shortage of Calor gas left some without hot water and unable to heat their homes over the Easter weekend.

In another, they have to move a load of Calor gas tanks and some plastic waterbutts apparently full of snooker balls.

Calor Gas bottles have a distinctive shape and colour; if you tried to make a pressurised cooking gas container in the same shape and colour, its lawyers would doubtless grab you on a "trade dress" suit.

On these dark evenings, my dad would wheel out an old Calor gas stove that we used when camping.
