A7-ACF flown QR1130 @ 27/1 has being to maintenance in Zurich back in 2012. So probably is not that because the news would be out before.
My guess is A7-ACA flown QR1130 @ 17/1 who positioned to Zurich at 10/11/2013 according to
theqatarsource.
A7-ACA is also the oldest A332.
But again... I'm just guessing
