Air Gregory, Denham
Earl
The mists of time and all that! Air Gregory at Denham, I seem to recall had a few machines (5/6?), though my only input was on occasion to visit to look at/fix an Alouette 2 that they had and also a Gazelle (owned by a gentleman called Mr Absalom, I think). And that's where it all gets a little fuzzy I am afraid. I recall the Chief Engineer (AM) and another contract chap from United Biccies called Russ something-or other. And the fact that Company would use reverse thrust on their King Air to back it into their hangar - at the other end of the airfield.
So not a lot of help - more red wine then ~ VFR
