The same photos as in post 3, above, appear in the Aero Modeller Annual 1953 (page 61). The text states that the logo with the banking gull is hand-painted in black, yellow and white on Proctor G-AIEP. There is a photo at https://www.flickr.com/photos/dwhitworth/5450165913/in/set-72157626751303608
The same article also illustrates G-AHWU with a similar logo on the fin, but with a blue background.
