ORAC,
You describe the AD set up of 1979, which is why I chose that date. It may be out a few years either way but it iS true for the majority of the period post 1957 until the increase from 5 Lightning squadrons was proposed. The 1969 reformation of 43 Sqn was the first stage of that process.
Oh, and you slightly exaggerate. It was ONE F4 sqn at Coningsby, No. 29.
