In a leaked document, widely believed to have come via the Grauniad, it is alleged that "stan bycompass" is the nom de guerre of Petty Officer Andrew Upper-Yardman, who joined the Navy after having failed selection for the RAF Police.
Having pierced his promotion ceiling as a result of an unfortunate misunderstanding with the Master-at-Arms of HMS Nancy, a shore establishment not a million miles from Soho, Stan/Andrew is counting the months to his pension.
Meanwhile, he is to be seen, together with his pet Chihuahua "Snowdrop," regaling the patrons of the lower-class pubs in and around Helston with his stirring tales of derring-do as a SHAR pilot in the Falklands. The men in white coats cannot be far behind.
