No, 1T is the prefix for all the armoured bulldozers Caterpillar built for the British, both D6(Armored) and D7(Armored).¹ The D6s were 1T3001–1T3045² and the D7s were 1T1001–1T1138.


¹ Which, BTW, appear to be Caterpillar’s actual designations, rather than D6A and D7A that everyone uses nowadays.
² But there is a photo of one marked 1T3060 as well, which has yet to be explained AFAIK.
