Hard to tell given the quality of the pic. Mauboussin Corsaire, Farnborough?
Nope, not enough wingspan...but after stressing over it for a couple of days I think I have remembered! I believe it's a Druine Turbulent. The location is Sywell in Northants. Yes you are correct that Farnborough is older, but it has not been a
public airfield for almost 80 continuous years like Sywell..
