Somebody earlier asked about a list of 6 AEF Chipmunks ...
In Sept 1978 at Abingdon they had - WB586/A, WP901/B, WK589/C, WP805/D and WZ877/uncoded (but had previously been 'G').
Their full complement in September 1988 at Abingdon was - WB586/A, WP901/B, WK589/C, WP805/D, WP914/E, WZ847/F and WP786/G.
In September 1989 at Abingdon they had - WB586/A, WP901/B, WP805/D, WP914/E and WG786/G.
I might be able to find details of what they operated between 1978 and 1988 but it is likely to be almost the same aircraft.
