265 used to be full NAC anyway.
NAC 0405s with their rear ad frame/holders and blue seats with
white panelled blowers above your heads...
That was in the 90s before SBST's feeder bus services started
getting AC fleets.
265 and all other AMK feeders/Townlinks became FAC fleet
somewhere in 2002 after all the 0405s were converted CAC (though
NAC MK2s and LAs ever did on some AMK feeders for a short
while).
Somehow in 2005, NAC Scania N113CRBs were dumped only to
Townlink 265's route in AMK. Most probably due to more AC buses
needed during that period when SBST introduced several new services
in Bishan...
