Farnborough 1961

Hi,
Is there another oldtimer out there who remembers Farnborough 1961? I’m trying (have been for years) to pin down the identity of the aircraft in the high altitude,contrail height, flyover by Bomber Command that year. This was comprised of 8 Victors, 12 Vulcans, 10 Valiants and 10 Canberras and was meant to show what the skies of Britain would look like a few minutes after the 4 minute warning had been given in the event of a pre-emptive strike by Russia. Quite impressive it was too! This was a follow up to the V-Bomber scrambles shown at the 1960 Farnborough Show the previous year.
It would be a help just to know at least the squadrons involved. All I know is that the Vulcans did not come from Waddington!
