Those who joined BP Tankers in the 50's and 60's would have had one of these recruitment brocures of which I have this one and the later one that I will also post a scan of.
There is a cutaway drawing by Laurence Dunn of 'British Duchess' inside this version.
For anyone who wants one now...
Lifeboat down at Little Aden, 1970. Sadly, most names have gone, 2nd Mate steering with Ian Doctor, Junior Engineer, alongside. Three in the foreground were, I believe, E.R. ratings. The vessel in the background may have been British Power, memory fading fast.
