Gulf Falcon still has one B747-136, the former G-BBPU (cn 20953), which has gone through a couple of registrations since acquired : first P4-GFB, then 3C-GFB. Could be 5Y-GFB by now, as the airline seems to have settled on Kenya as a country of registration after experimenting with Aruba (P4), Equatorial Guinea (3C) and Swaziland (3D).
Their other B747-136, the former G-AWNC, is reported to be at Marana, AZ (MZJ) for scrapping (Maastricht was a stopover on its final ferry flight). This one was wearing 3D-GFA (ex P4-GFA) when last seen.
I seem to remember reading somewhere that they'd acquired another B747-136 to replace the scrapped one, but cannot confirm that.
