Smudge,
I agree with you. Our groundcrew were just as scruffy as any other while on the job (which they did magnificently under very difficult conditions, with little protection from sun and rain, often through the night to keep us flying).
Looking at your pic, I am beginning to think that these seven may not be groundcrew
at all, but just seven lads " 'avin' a larf" witn their doctored pic of
the B-29 in the backgound.
Danny.
