My Missus - who is much better at aircraft recognition than I am reckons you really need to know your
onions (ahem) to ID this a/c manufacturer
Funnily enough I lived (for 4 years) very close to the factory where this a/c was built and the landing ground which was used for flying.
Not a major name in a/c manufacturing but they built hundreds of a/c on sub-contracts during ww1.
