Harry - not sure where my post went - I may have deleted it when adding the photos, now found below, of the spoiler panel.
I offered my thoughts on what the recovered parts on display were, which is new information - the most interesting parts I think are the two, intact overhead bin covers and the doctor's kit.
We cannot say anything from the photos about the F/A seatbelts. It's not from L1 where the CIDS is as there are no traces of any such displays or equipment on the bulkhead in question. It could be from any section - we just can't say.

It's a spoiler panel from one of the wings.
The torn section in the center is where the hydraulic cylinder that extends the spoiler is attached. The attachment points to the rear spar wing structure can be seen at either end.
