They are Argoseys, I've stuck about 140 photos onto discs, copied from slides. I'll upload some more, but my internet link's pretty crapy - dongle only, too far from civilisation (ie 10 miles!) to get it down a wire) Looking at the slides, I think there's two seperate shows here, the weather's sunny in one, cloudy in another. Two Belfasts - "Ajax" & "Spartacus".
The Beverley appears to be XL148, scrapped 25/3/70 at Shrewesbury. It might be , which is preserved at Aeroventure (Doncaster?)
Other planes include Hawker Hunters, from 27 Squadron; one's XG191. BBMF's Lanc, without its dorsal turret, part-visible are Hawker Tomtit K1786 and a Hart/Hind K205x, Beagle XS782, Vulcans XL367 (?), XM603 (Preserved at Woodford), XM574(Scrapped), a Victor (no serial visible), Anson "FV-X", Buccaneer, Concorde (the one now at Duxford?), a Meteor with a very pointy nose, Percival Proctor IV G-ANXR,
Good shout about the Swift, it does look like one to me too.
