Jeremy says not and without the telescopic sight fitted either.
However, I seem to recall Pargeter said the gun had both the silencer and the telescopic sight fitted the weekend before when he visited WHF.
The silencer / sound moderator normally being used when shooting vermin such as rabbits........ I believe the silencer / sound moderator helps in stopping the vermin from running away so quickly after a first shot is fired.
The reason I ask is that if it had been left on,,,just the silencer,that is,,,then Sheila had already used the rifle downstairs,,,found that it was too cumbersome with the silencer on,removed it with bloodied hands ( reason why her blood was in the silencer ) then put it in the cupboard,or even left it around and someone else put it away. The sight,I could more or less guarantee,wouldn't have been attached as it needs a philips or specialised screwdriver to remove it and I don't think Sheila would have been up to that.
I don't even think that Sheila would have put the silencer in the cupboard,,as it would have been just left anywhere,possibly found later on the floor somewhere. However, it wasn't used. No wonder it was contaminated the amount of times it had been handled.
