We can't possibly ever get too many Chipmunk photos! Trawling through my 6 AEF photos, I've come up with the following which may be of interest:
WD331/J - Lyneham, 25.6.1994 (Ken Slade).
WP778/Y - Waltham 19.4.1970 (Andy Anderson).
WP860/Z (Brian Stainer)
WB586/A Uncredited but dated August 1984.
WZ847/F, uncredited, Bruggen June 1991. I love this photo!
WZ877/G, Binbrook 28.8.1982 (Shaun Connor).
