Marlowe who got his pilot brevet in December 1915 in Chingford stayed there at least another month. He changed to Yarmouth in February 1916 for doing coastal patrol, anti-airship and submarine missions.
The scenery is likely at a coastal patrol - so he might have moved to Yarmouth early that month. Only the aircraft does not seem adequately armed as a zeppelin-interceptor. And I was not able to locate any mention what kind of aircraft were hosted there that could be what we're looking for.
I think this is not to find with the web.
