This piece of standard plumbers pipefitting was combined with a four inch nail, a .22 cartridge and homemade explosives to manufacture an Improvised Explosive Device (IED). It was discovered, along with twenty eight similar IEDs, in Carrickmore Co Tyrone in February 1974. At the time the British Army was tasked with rendering safe IEDs.
