Hipper,
I think I've been well wide of the mark! The airfield looks nothing like Wyton and I'm sure Huntingdon wasn't that small in 1946!! (damned bi-focals!!)
Huntingdonshire was never a very large county but I can't think of any of the wartime airfields that had that particular layout. Maybe the subscribers to 'Aviation History and Nostalgia' might have an idea.
