How to find out which tail number operated a specific flight



Maybe its a long call, but I’ll give it a try. In 2009 during my honeymoon, I flew a QantasLink 717-200 Darwin-Cairns on 28.08.2009 at 7:00, flight QF1871. Is there a way to find out, which of eleven QantasLink 717’s operated the flight? I want to build a model of that particular one for my 5th wedding day…
