I was in a bit of a hurry when I posted yesterday and realised that perhaps a bit of a translation might be in order.
No. 3 AAP (Aircraft Acceptance Park) was at RAF Mousehold Heath and was set up to receive aircraft from manufacturers in the Norwich area including Boulton Paul and Mann Egerton. Boulton Paul used the site after WW I and it became the first Norwich airport in 1933.
No. 2 FTS (Flying Training School) was at Duxford at the time mentioned.
No. 24 Squadron was at Kenley.
PD (Packing Depot) Ascot got the aircraft ready for transportation to India.
AD (Aircraft Depot) RAF Drigh Road was near Karachi (which was in India in those days).
No. 27 Squadron were based at Risalpur (and later Kohat) in the North West Fontier.
Hope that helps.
