All this G/E talk has reminded me that on 48 at Changi we had 2 US civilians attached to the squadron - one was the Lockheed rep' and the other the Allison rep', and they sometimes came en-route with us, particularly to Kai Tak where I guess they liaised with HAECO.
I wonder if there were any reps' attached to Thorney, Fairford and Lyneham in the early days?
