-OGT going to WS was another airliners.net myth, think somebody tried to put some dots together as one of their actual ex QF B763's is being registered C-xxGT and drew some conclusions from there. It's actually in Paya Lebar being converted to a freighter for National.
It's a bit like the first 4 QF A332's had weaker floors in the J cabin and the first 4 JQ Dreamliners were delivered with reduced thrust engine pylons..
