This man wears an RAF cap and cap badge. His rank we cannot see but his half Brevet with the letter B tells us he is a Bomb Aimer.
Medium and heavy bombers carried crew numbers which varied in quantity depending on the size of aircraft. The pilot and co-pilot wore full wings. Other members of the crew wore half brevets which was a single wing emerging from a wreath which contained up to three letters.
These letters indicate the crew member's function.
