I assume that the first registration (that of the Hawk) has been mistranscribed and should be G-ACLI.
I wish you luck, FournierF5, in your quest to identify the 'missing two' - but you may find it no easier than my quest to identify the 'missing three' civil aeroplanes stored at Lympne Aerodrome which were destroyed in the 1940 German bombing raids on the field. So far I've identified ten of the thirteen, but I'm having difficulty with the remaining three.
