OOPS, sorry I obviously had a bit of finger trouble typing into G-INFO.
I guess there a slight possibility of the KD being the last two letters of a foreign registration.
The last two letters of the under wing registration are obviously KD. G-ABKD was a DH60T Moth Trainer which would have had a forward facing exhaust system. The aircraft in the picture clearly has a long exhaust pipe exiting behind the cockpit which makes it a DH60G Gipsy Moth and therefore I think that it is safe to assume that it is indeed G-AAKD.
As far as I am aware the Do17 remains are still at Cosford, not Hendon.
Looking at my old spotting books, I see that I first saw G-ABUS at Sandown IOW on 29/5/67. I can’t remember its colour scheme at the time.
The first Swift I saw was G-ABUU at Portsmouth on 3/10/65 at a fly-in. I do remember its colour scheme being red with black striping. For a while it was my favorite aircraft until I saw Cosmic Wind G-ARUL “Ballarina” at the Kings Cup at Baginton on 13/8/66 which was love at first sight! I remember that I was quite upset when she was written off at Halfpenny Green later that month. A few years I saw her “recreation” in a hanger at Duxford I knew that she existed but it was a surprise to see her. Although wearing the same registration, I understand that little or nothing of the original Ballarina lives on in her and she has lost something it not having the ribbed control surfaces..
“Edit: I think that he was flying Miles Hawk Speed Six G-ADGP but, if so, can anyone confirm that, please?”
Yes, according to the book I referred to in my earlier post.
First was Proctor 1 G-AHUZ.
Second was Miles Nighthawk G-AGWT.
Third was Hawk Trainer G-AGLK.
According to Peter Lewis – British Racing and Record-Breaking Aircraft – Putnam 1970.
No information on how G-ABUS did.
Obviously, Kings Cup winners did not get to keep the cup itself. My understanding is that the replicas were given to the winners to keep. So this one would have been given to Schofield, the pilot of the 1934 winning aeroplane.
This is a pic of the simulator at Brooklands. Maybe not good enough though.

It could be a fake livery for a film.
There was a Riley Heron conversion in the 1986 film “Club Paradise” but that was liveried as “Joe’s Airlines” and was apparently N600PR.
“Yak 3” F-AZIM has now been parked on the grass at Lee-On-Solent for over a week. The long standing red star on the fin has now been over painted with the Ukrainian flag and crest.
Spit TR9 SM520/G-ILDA was doing circuits to-day so probably doing pilot training rather that joy rides.
My initial thought was the front (of three) nose gear door from a Beech Turbo Mentor. However, having looked a photos of Turbo Mentors, it isn’t that. I do feel that it’s a U/C door off something.
That’s what I was thinking too, but it’s difficult to judge the size from the pictures.
My immediate thought was Ford Trimotor or possibly a Fokker Trimotor which was very similar given the likelihood of some inaccuracies in the drawing. The fin however is much more Ford like.
Some hunting around the web brings up that the Liberian air mail service was started with a single engine Waco before a Ford Trimotor replaced it. So a Ford Trimotor it is then.
Thanks for that.
There seems to be something odd about the serial number. It looks like it is a digit short. The only copy of the picture that I have is low res and therefore I can’t enlarge it to have a good look. Maybe it was a running ground only instructional airframe. Did the Fleet Air Arm of the time use different serials for instructional airframes? Also the cowling seems be off a different aircraft with the two tone paint scheme.
