Yanks ?
Well here we go after a couple of glasses of Vino Collapso and regaling wife with war stories of episodes past I remembered the name "Yank" Caldwell as the exchange gentleman who accompained us on our South African jollies, ring any bells with you Brakedwell (guess your name not from Argosy days as we only had "discing" - ground fine as I remember), just this afternoon dug out my "fuel trimmer and AWA yoke centrepiece" to try and make my brain work, ah nostalgia, not what it used to be.
