MMTB - AT & ET Registrations Please

[MAN_LOVER]

I have lots of books and magazines.... but i can't find the answer.....

How many M&MTB buses had AT and ET series plates and either a list of plate combos or the block used please ?

[1whoknows]

This isn't a complete list but there were Leyland OPS1s registered in the ET 370, ET 380, ET 390 ET 410 and ET 420 groups and there were AEC Regal IIIs in the ET 340 and 350 groups ET 430s and 440s, AT 020, AT 030, ATA 050, AT 060, AT 070, AT 080, AT 090, AT 500, AT 510 and AT 540 groups. Of course a number were later rereg onto Hxx xxx series plates.

System Improver probably has more details.
