I've got a HUGE framed photograph of the same airframe (the first Comet 4), possibly taken on the same flight. I purchased it online from the RAF Museum Shop about two years ago and had it professionally framed in NZ native rimu wood. According to info on their website, the photograph was taken in September 1958.
