Poison,
MSN660, in photos on !!!!!!!!!!!!!!, would clearly appear to have the taller tail of the non-FBW A330. Also, the build date would suggest that it was produced before the FBW tails were added to the A330.
Have a look at the mod status in the front of your FCOM and confirm that MSN 660 was fitted with mod 49144. If it has, then I'll eat humble pie.
