would say closest 707 is a 436 while the one further aways is a 300 series

Looking at the bigger version I agree. the far jet is a super vc-10 but the nearest 707 has different engines (not RR) and an undertail fin). I think this might have been one of the two original BOAC 707s that went to BEA Airtours in 1972 and I think they were registered g-apf something.
