I didn't realise you included arigun paraphernalia. For the classic rifles I, obviously, need classic scopes which need classic mounts which are, in my eyes, Apel.
Then theres the books. Apart from the four books by Walters theres the many volumes of the Blue Book of Airguns and those by D R Hughes plus a few more odds and sods.
Then theres the (early) editions of the airgun magazines including Sporting Air Rifle.
I cant see no line.
