I'm pretty sure that -MBT was a Sydney-based aircraft so would in all probability operate ex SYD, MEL & BNE to Asia and SE Asia. It was a long time ago!
With respect to -MCF, I recall that there were a number of complaints from F class passengers as the 'arms' that lifted the nose door interfered with what could be seen from the windows. I can't remember if those seats were subsequently blocked from sale, or last allocated or what the fix was.
I never had the dubious pleasure of even seeing the TowerAir 747s but I think everyone from the CEO down were very pleased to eventually see the back of them. I don't think CA was ever forgiven!
