Wasn't actually on Dolphin, but was at Leith Nautical college (which was very adjacent) 1968-70.
Prince Phillip was due to do the honours re the new dock gates at Leith and he was due to go past Dolphin and LNC enroute. A few of us went out to see what was about, and saw that a number of the Dolphin lads had been paraded in their Battledress uniform. The Duke saw them from his car, and being an ex seagoing person, had his people stop and he went and did an 'inspection' and from what I recall he seemed to have a few words with them (we were a number of yards distant), and off he went to continue his day.
Was anyone here involved in that?
