They are not fake first, second: give the man a break he tried his best and beside Centurian mk1 all were made before the end of the war
for Centurian Design
In 1943, the British War Office mandated the Directorate of Tank Design to start working on a new heavy cruiser tank. The requirements stated that the new tank should be capable of withstanding a direct hit from the infamous German 88 mm gun, while providing greater protection against mines as well as staying under the 40-ton limit imposed by logistical constraints. The tank also had to offer a good cross-country capability when offroad, a high reverse speed was required but not a high forward top speed. The new project, called A41, had to surpass the Comet tank in all areas except the main armament for which the 17-pdr gun was still deemed effective enough to deal with enemy tanks.
here is the thing 6 Centurian mark 1 was sent to Belgium a month after the war so they are not suitable to add to the tech tree but prototype centuries and pilot Vehicles are, since they were finished before war’s end

you see these were finished before war so in my mind all OK
By the Second World War’s end, only six Tortoise prototypes had been built, and these were not delivered until 1946. A few of these 6 (exact number unknown) were sent to Germany for testing after the war as part of the British Army of the Rhine (BAOR).
During trials, it showed its reliability. The gun proved incredibly effective during tests, with the tank itself providing a stable gunnery platform. A serious problem, however, was the logistical issues created by the sheer weight of the tank. It required 2 heavy-haulage trucks to move and carry it. Also, not one of the British Army’s mobile bridges, such as the Bailey Bridge, was able to support it.
And about tortoise 6 were made before the wars end so its OK
