Hi Steven,
Mr. Smith (UK Aikikai) teaches in Cradley, the dojo website is here -
http://www.renshinkan.co.uk/
Mr. Cottier is (or was) the chief instructor for the Hong Kong Aikido Association however I think he may now be linked to the British Aikido Federation although I can see no mention of him on their site -
http://www.bafonline.org.uk/ perhaps he links with them whilst he is over here in the UK?
Jim, I think Mr. Smith was awarded with M.B.E not the O.B.E.
