The Gloster Gladiator was one of the last biplane fighter aircraft to serve during World War 2, and despite its obvious obsolescence, served for the British air service surprisingly well on a number of fronts. It made a name for itself in the early middle eastern desert war, and went on to serve in Greece and even further with a number of foreign air services.
I recently built and reviewed ICM’s excellent Gloster Gladiator Mark 1, so I will mostly be pointing out the differences between the two kits. The most noticeable is the new three-blade propeller replacing the rather clunky two-blade unit of the Mark 1. Other differences are more subtle, including a new control panel and front windshield. Only a small additional sprue is included to offer these differences, and you still have all the Mark 1 pieces if you prefer to go in this direction.
