Brian 48Nav,
Not sure about those you mentioned, but, the "Lockheed Rep" at Colerne, when I arrived in 1971 was a great big Texan I believe. I can't remember his name (though Jim comes to mind) but he wore Cowboy boots and a large white Stetson. At Christmas he, on behalf of Lockheed, took both of the Base 3 (Major servicing) Teams to a great place in Bristol and feted us to all we could eat and drink. I'm sure he did the same for the other teams. Such events stopped pretty quickly once the Lockheed reps were withdrawn and Marshalls of Cambridge provided the civilian link. Hope that helps.
