When I started my Career at the War Musume in London I worked on board HMS BELFAST which lies at Anchor at London Bridge(Pool of London. Our supervisiors were called Leading Hands and killick was the Naval term for A lEADING HAND.
I was employed under the title of Yeoman.

Next came leading Yeoman (Killick)
Then came Chief Yeoman. Hms Belfast is still honoured in flying the Ensign despite she has been decomisssioned. We still do the Colurs at sun up and Sun down.
Hope this helps Pierre.
