File Description: Ifly B737-700 Payware Livery MartinAir
It is a real existing Livery from Netherlands MartinAir. I am not sure that they operated with 737. So it could be possible that this Livery is more fictional. No worry - looking good on 737.
You need Payware Ifly B737. not more. copy the texture folder to aircraft ifly737-700 folder and change the aircraft.cfg. That is all.
