brakedwell; two of the Ansons were PH858 and '859; if I could find my 3822 I could possibly give more on the others. The Valletta as far as I recall was 'standard' white top/natural metal undersides with broad blue cheatline. If Honey Monster sees this post he would be able to enlarge as he scrounged more than I did.
There was a pilot (Flt Lt Colbourne?) with a badly burned face. His takeoff technique in the Ansons was full throttle down the runway, tail up, then retract the undercarriage without rotating!
