I would like to reiterate, that two silencers lie at the heart of the investigation
One [belonging to Anthony Pargeter] parker hale silencer, 7 inches in length, containing 17 metal cup shaped baffle plates, purchased in the period of 1980 and the 31st October 1984.
From the 1st of November 1984, the product manufacture [`Parker Hale Silencer Ltd'] replaced the outdated unit (old type silencer) with its latest upgraded version (new streamlined silencer model) which was only 6 and a half inches in length, and which only had 14 cup shaped internal ('metal') baffle plates [belonging to Neville Bamber]
