John,
Actually a 'Master Gunner', who had a Gunner's Mate as his underling to look after the Gunner's Party. Pedantic I know but as I qualified as Master Gunner in 1974..... Even more disconcerting is that my first, short, appointment was as the Master Gunner of HMS VICTORY where one of my claims to fame was escorting HM Queen Elizabeth the Queen Mother to the heads which were in a block ashore! There is more to that tale but the rest is reserved for a shoreside dit.
