British Diplomatic Service Uniforms Dress Regs 1960s

[quicksilver]

Can anyone please suggest a book which lists the details or dress regulations of British diplomatic uniforms. I am keen to know the details of Class IV and V 1960s uniforms worn in the Arabian aka Persian Gulf?

I am not sure that they have changed since the 1921 regulations were published, have they?
