Summary
This can be considered a “diorama-in-a-box” in that it contains everything one would need to create a nice airfield diorama. There are some frustrating fit issues, so I would recommend this kit to any modeler with a good dose of patience.
Background
The Spitfire MkVII airframe was based off of the MkV. It incorporated the improved Merlin 61 series engine. It was designed as a high-altitude interceptor and thus had a pressurized cockpit. It also had extended wing tips and the later large (pointed) rudder.
The MkIX was a later variant incorporating the Merlin 66 and later engines. Armament consisted of two 20mm Hispano cannon in the inboard position and four .303 browning machine guns in the outer positions. While most had the standard round wing tip they could be fitted with the clipped wing tip for low level operations. This variant could also carry a 90-Imperial gallon slipper tank as well as bombs and rockets.
