G-AVMT BAC One-Eleven 510ED of British European Airways (BEA)
BEA were a somewhat late user of this type compared to the independent carriers.
When BEA initially brought the 1-11 into service standard 'Lego Box' Colour Scheme was initially applied, but this did not 'work' for this Aircraft Type and when this picture was taken, had been replaced by a much 'cleaner' livery with Super one-eleven titles on the Tail Fin.
