BTW, are you sure this is a leased aircraft? Philippines always flew GE powered -200s (although had a couple of JT9D powered aircraft, which were the ones I always found myself on) (nearly always, anyway).
There aren't many GE 747s around, I would think this is part of the original PR fleet, and maybe has been returned FROM lease? I would expect that if they leased iron for a season (a) it wouldn't be painted in full livery (b) it would be P&W powered (c) it wouldn't even be a 747 and (d) it wouldn't have a full Philippine reg.
Just a few thoughts. Nice photo BTW.
fly Saha Air 707s daily from Tehran's downtown Mehrabad to Mashhad, Kish Island and Ahwaz
