 In the early stages of the investigation into the bombing of Pan Am Flight 103, the Scottish police showed Bollier a photograph of what he said was a brown 8-ply timer fragment, from a prototype timer that was never supplied to Libya.At the Lockerbie trial, Bollier was asked to identify a green 9-ply timer fragment from an MST-13 timer, 20 of which had been delivered to Libya.He wanted to dispute the evidence but trial Judge, Lord Sutherland, did not permit him to do so.
