Two of these sorties are described on page 151 of Nimrod Rise and Fall by Tony Blackman, together with a chart (for one of them) and photo of the relevant page/entry of Dave Emmerson's log book. My eagle eye notes that DE recorded the P1 in his logbook, this may or may not have been the Crew Captain (I think not, but I'm not 100% sure) so don't let that confuse you.
For interest, some of us hand-amended the logbook by striking thru' "Pilot" and changing it to "Captain", thus enabling us to correctly record the aircraft commander.
I mention this detail purely - of course - for the sake of accuracy and to facilitate your research. It is not in the least an attempt to wind up the two-winged master race
