EDIT - Ian's pictures can now be found
here.
Very nice Ian, but surely these are all mark 1s? A pair of TSOs and an FK. Later mark 1s and early mark 2s were heavily covered in formica or were by the time I remember them in the late 1980s.

PS - the grey moquette is to a pattern known (I think) as 'Trojan' and, although the seats must have been reupholstered looks quite nice. The horizontal striped shades of brown in the FK also look familiar - was this something usually found in mark 3s?
@Bob-65B is your man for this sort of thing.
