From the COA. It seems the gun cupboard was in Nevill's office den -
Recovery of the sound moderator 73. On 10 August 1985 members of the family, who were far from convinced that Sheila Caffell had been responsible for the killings, went to White House Farm with the executor of the estate, Basil Cock. During the afternoon David Boutflour found the sound moderator together with the telescopic sights for the murder weapon at the back of the gun cupboard in the downstairs office. His father, his sister Ann Eaton, the executor and the farm secretary all witnessed the recovery.
