I recently picked up this old (originally released in 1978) kit and uncharacteristically, rather than stashing it away for a few years, I decided to build the thing! This had originally been part of the Matchbox 'Orange' range, which if memory serves were priced at about the same level as Airfix Series 3. Which explains why out of a range of around 50 Orange aircraft kits released in the 1970s I only recall having three: Beaufighter, Swordfish and F-16.
Anyway, back to the Warthog. The parts - moulded in three colours - were largely flash free and not intimidatingly numerous. Initial build progressed smoothly enough.
The decals related to a prototype and a pre-production aircraft.
