noblues - from the use of 'ASR' I take it you are BA? Please NB that ANY MEMBER OF THE CREW can raise a safety report/MOR ('ASR'). It does NOT depend on the 'colleague', so if you feel it warrants one, write it! Indeed, it is your DUTY to do so.
PS Check 'Tech Log' and 'Standby altimeter setting' thread - it is relevant to this.
