Mines a premier d series, bought it 32 years ago for a tenner ,boxed and is still in excellent condition. Still has the tr robb synthetic head and spring I fitted all them years ago and still powerful and accurate. Used it to dispatch corvids when shot gunning. It's the first collectors gun I'd bought and even when I sold up all my pistol collection I kept this. Told my son if he ever sells it after I'm gone I'd haunt him!!!
