Thanks for the replies chaps. Had a bit of free time and no disturbances, so i went through my SD card, and despite most of the photos being artistic, a few registrations became apparent which might shed some light on the A340's. There were 2 Air China examples, with one reg visible F-WJKO, another EI-FMH and CS-TWT, all with smaller 'hairdryer' engines and the new looking all white A340's at least 5, only reg visible F-WJKK and these all had the larger engines (RR Trent ?) and on closer inspection look like -600 variants, as the angle of viewing foreshortened them optically. There were also a few Air Namibia A340's further along.
The A350 on the breaker's side of the airfield minus engines has a small '04' on the lower tail, hidden under the 'A' of the 'A350', so it would appear that it was indeed msn 004. It looks in the photo as though it's been mothballed temporarily and ready to go at short notice engines allowing! It appeared to be in Airbus' colours, perhaps the other side had Qatar colours ?
The breaker's compound was very full, many airbus present, Air China, Cathay, DHL, Air France, Virgin Atlantic, Nordwind Airlines and TAM. Surprisingly there were a few 747's and 767's being cannibalised, bearing in mind the proximity to Airbus' homeland.
