Great project Leigh!!!

, (I am sure I can talk you into doing more than just 7 707s...after all there are just so many great schemes, why limit yourself

).
As promised, please see what I have dug-up for you so far.
Note that the Qantas 707-138B in these photos feature the very short-lived "interim" colour scheme that appeared between the original 707-138 delivery colours and the first of the
V-jet schemes. However the upper wing details seemed to remain pretty constant.
Note also that the over-wing exit directional escape arrows was not yet a requirement when these photos were taken.
