Desert flower Im sure that WZV was cross hired... And was maintained by some mob out of ADL.
ChaseIt, it may well have been cross hired, however West Wing were using it on the mail run out of Port Augusta. It may have had some maintenance done in ADL, but I know a lot of it was done in ISA - because sometimes the pilot used to go up in WZV & come back in one of their Barons.
