That will presumably have been before the "share split", when one old Air Miles award became (IIRC) ten new BA Miles? So that would have been the equivalent of 2 Avios per £1 spent, which would be broadly the same as it is now (rounding differences aside).
I remember those menus. They certainly take me back!
