According to testimony delivered at the 1975 trial of the six men wrongly convicted of the Birmingham pub bombings, the bomb planted inside the "Mulberry Bush" was concealed inside either a duffel bag or briefcase, whereas the bomb planted inside the "Tavern in the Town" was concealed inside a briefcase or duffel bag (possibly concealed within a large, sealed plastic bag) and Christmas cracker boxes. The remnants of two alarm clocks recovered from the site of each explosion leaves the possibility that two bombs had been planted at each public house; the explosion crater at each location indicates that if two bombs had been planted at each public house, they would each have been placed in the same location and likely the same container.
