Thanks for all the comments.
PN.. I dont think that the FOI would work as Im a civvy and these pubs are military restricted. Althopugh I have a security rating the system couldnt cope with that scenario. Even if was 40 yrs ago
I have now got what I needed and thanks to all concerned.
Am still looking for the poster in the first post and if anyone has any similar docs such as bang seat posters, manuals, etc I would love to give them a good home.
