The 13th of August examination record has the silencer being 6.9 inches long. The 25th of September examination record has the silencer being 17.6cm long.
6.9 inches = 17.526cm
I guess Joe Stone never brought it up because its fictional?
In their promotional literature for the Standard MM1 type sound moderator Parker Hale give the specifications as:
“Length - 175 mm (
6 9/10ths of an inch)”
On 25 September 1985, forensic scientist Brian Elliott from Huntingdon Forensic Laboratory created an examination record of the: “silencer for rifle SBJ/1”. The description he wrote of the silencer stated :
“1 metal gun silencer – sound moderator. Length 17.6 cm [
6 9/10 inch].”
On 29 and 30 April 1986, Malcolm Fletcher a forensic scientist from Huntingdon Forensic Laboratory conducted various tests on a .22 rifle (taken from the scene) and a silencer and a sound moderator. The tests results referred to the length of the rifle barrel. Malcolm Fletcher stated :
“Barrel length 23 ¾ inches (60.3 mm)
On 5 November 1993 Malcolm Fletcher stated :
“.22 rifle with silencer attached was 28 ¾ + 6 9/10 = 35 13/20 inches or 175.2 mm”
On a JW/16 Laboratory examination form dated 12 September 1985 for an examination of the rifle and silencer, Malcolm Fletcher details :
“O.L. [overall length] 43 inches. With silencer attached 49 ½ inches,
Length of sound moderator measured
6 ½ inches 165.1 mm”
Malcolm Fletcher then measured the M.T. [Muzzle to trigger length] he stated:
“M.T. 28 ½ inches with the sound moderator 35 inches.
Sound moderator’s length
6 ½ inches or 65.1 mm.”
Malcolm Fletcher then measured the rifle’s barrel length and stated:
“B 23 7/8 inches with sound moderator attached 30 3/8 inch: 165 mm”
Glynis Howard and Lesley Tucker examined a “silencer for rifle” SBJ/1 on 13 August 1985 :
o “Silencer for rifle dated 13.08.85, SBJ/1 crossed out DB/1 inserted. Description One black metal silencer
6 and 4/10ths of an inch long. 166.1 mm”
A General Examination Record completed by Malcolm Fletcher dated 12 September 1985 stated:
“DB/1 was 7 inches long or 177.8 mm”
In 2002 Forensic Scientist for the Crown Martyn Ismail gave evidence in his 23 August 2002 witness statement that :
“The moderator was a black tube, 177 mm in length”
[177 mm = 7 inches]
In undated notes taken at around the table meeting Malcolm Fletcher stated :
“The rifle (sic) [presumably he meant the silencer]was
6 ½ inches in length, photographed and referred to as photograph 65 (Never disclosed).
also :
“Length of weapon. 43” long 49 ½ inches with silencer. (i.e.
6 ½ inch silencer)
Therefore numerous examinations of the silencer by various forensic scientists showed that two different silencers were being examined at various times during the process of investigation. Malcolm Fletcher and Essex Police convinced the Defence and the Courts that the case featured a single silencer/sound moderator and yet the above documentation shows that there were two silencers, one 7 inches long and one 6.5 inches long. Presumably, the 6.5 inch silencer was not a Parker-Hale. Malcolm Fletcher handled both silencers and therefore knew about the deception before the case went to trial.
