It's been all over the news down in Guzz.
@buffersduffer - I do not think it is the same person but that cine-op guy at 1:22 does bear a close likeness to the CPO Weapons Mechanician Jim Bowen BEM whom I served with in REVENGE during the mid/late 1970s.
I never saw a Chief Jack Dusty with or without a set on any boat I served on. I liked the part where they said the boat had been away so long that when they got back to the loch it was raining. Could have been the next day or even later the same day.Even with the age of the PSOFs on here, I doubt if anyone will recognise people from this 1960 movie! I confess to recognising the Main Gate, as we used to go to kiddies parties on Adamant!
