They do for the D6(Armored):

I haven’t seen a list for the D7-series, but I would suspect they appear there too?

According to this page, only the armoured ones had 1T prefixes.

Actually from 1944, according to that same site. I get the impression from that that 3T was the next prefix used for the D7 after the 3M series reached 9999 (the 1T D7s are basically 3M-series tractors with armoured cab etc.) while 4T is from another factory.
