I don't believe Nigel is suggesting there was an "order" to produce 2000 carriers. Rather, I think, a block of 2000 numbers, was allocated by the war office for Australian produced carriers.
I guess Breaker Morant's influence came in here, and the Australian authorities chose not to follow Mother Englands directions.
And so today I have learned that Aust. built LP2/2a's never had a "T" number.
ps. Mk1* were Canadian.
