The confusion I think with 183 Squadron is that the pilots did some conversion training on the Tempest II during september 1945 converting them from the then squadron Spitfire IX aircraft but the aircraft did not join the squadron.

And also the following the Tempests of 54 Squadron were ferried to 20 MU at Aston Down during October 1946.

I can confirm that the “test pilots mess” does still exist near to the junction of Sutton Lane and Little Sutton Lane but is now a private residence.
From memory of a visit to Langley sometime back during some research I am undertaking.

Westland Scout grey/green colour and Chipmunk presumably G-BARS in formation over Henley-on-Thames routing to Yeovilton? at about 12.30 pm

The Heinkel model looks like the example that PPS at Booker had up for sale recently, interestingly the wings are from the Waxflatter Ornithopter from the Young Sherlock Holmes film I had been told that this had been sold at auction back in 2015 to the Middle East but it appears maybe not?.

THE CHANGING FACES OF COWLEY WORKS BOOK TWO by CAROLE NEWBIGGING AND TREVOR WILLIAMS published by Robert Boyd Publications covers the war years of Cowley and has some good images of Tiger Moths on the production line as well as pictures of the metal recycling area with aircraft remains, a good little book.

G-AFKX was based on Mk.I airframe (contrary to the usual photo captions) originally allocated serial L1606 and I believe a replacement L1606 was built, because it seems to have the shorter wing root fairing associated with the shorter Mk.I nose. It should, on the other hand, have had a performance similar to the Mk.II, as G-AFKX had by 1941 been fitted with a Merlin 45 engine and metal wings.

Coincidentally many of the models in the film were made by Shawcraft (Models) Ltd who were based at Richings Park adjacent to Langley Aerodrome where of course the Portuguese & Hawker owned Hurricanes were prepared for filming. There models were also used in Reach For The Sky.
