 FACT: During the weapons robbery at the army camp, the character  played by Bryan Forbes is wearing a uniform with an RASC (Royal Army  Service Corps) shoulder flash. But he is missing the striped lanyard  which he should have been wearing over his left shoulder. Such a  lanyard, usually attached to a clasp knife stored in the left breast  pocket of the battledress jacket, was standard equipment for members  of the RASC in 1960.
