Pilatus Porter PC-6 Throttles

The Pilatus Porter PC-6's throttle lever is basically the same than other throttle levers as it "swivels' at the bottom, but differ as there are levers halfway up the stem pointing forward and going into the panel board.I am looking for this type of throttle set in XML format or similar that I can modify. Must be freeware of coarse.Any assistance will be appreciated. I can not thing of any aircraft (turboprop) with the same kind of throttle set.
