To fight the last war more effectively, and to control the airspace over the trenches, the Avro Avatar was developed. The four-gun turret below would be able to shoot down into the trenches as the four-gun turret above defended against enemy aircraft. The "Defiant" idea was also envisioned, whereas the Avatar would fly between enemy two bombers, raking them both broadside. Someone got the idea that such an Avatar, or especially a trio of them, could bank in a circle and spray bullets inward and downward---the first "gunship" was invented! When Britain was threatened by Sealion Invasion, the Invasion Defence Command (you can only see the "ID_", not the "C" of the special markings) commandeered every Avatar for strafing the beaches, including a New Zealander squadron (subject of the model).
For this ostensibly 1/72 aircraft, FROG's 1/96 Lancaster (actually two of them) formed the basis . Wellesley engine, B-24 ball turret, Halifax top turret, and other "subtle" modifications.
