I advised way back it's the two ex Great Wall China Freighters which are near new parked at Victorville CA USA ! One is in Southern California Hangar where QF has offices and store their QF 7x 747/4 and 3x 737/4.The other is pulled up to the Hangar ?
I think QF only thought about getting freighters because they went past them daily to get to their stored aircraft in Victorville and someone's lite bulb came on.
