The Tank, Cruiser, Challenger (A30) was a British tank of World War 2. It mounted the 17 Pounder gun on the Cromwell chassis to add heavier anti-tank firepower to the cruiser tank units.
This is the Flames of War blister, as with a lot of FoW models, you get a resin hull and turret and metal tracks and accessories.
The parts go together quite well. There were two challenges, one was fitting the square turret hatch and the main weapon. The hatch was slightly too big and needed to be trimmed. Whilst the main weapon needs to be glued to the turret with care to ensure it fits straight.
The track guards are very similar to the Cromwell IV, though the tracks have six wheels over the five of the Cromwell.
