I was a member of Nottingham/East Midlands UAS from 1968 to 1971.
I have my log book with the serial numbers of the Chipmunks I flew - mostly WD345, WK635, WP781 and WK609 - but not the aircraft letters. Can anyone help?
Unfortunately I have only one photograph of an EMUAS aircraft, WK548, at that time. (I would share it if I understood how to post it here.)
Has anyone got other period photographs that they would be prepared to share?
