I am sure the 700 with the airframe times/launches and landings for each airframe must still exist. In addition Engineering Control (ha !) at Syerston will also hold the information even if it were just in summary.
I think the documentation that 2FTS say has been destroyed is the log sheets and probably the Cadet Training Records which would have been held at VGS level.
That Engineering Control may have destroyed/deleted/discarded the job cards and information around older repairs carried out would not suprise me though.............. most of these records would probably have been held by the contractors who would then provide them for audit if required. This is what has not happened - I believe that the records were not archived and then when a problem occurred the audit showed up that the job records had not been kept................... ergo - fiasco !
