Something I missed in my last post:

Anthony writes, “The burial chamber was built around the sarcohpagus. Had they been forced to use another chamber due to the early demise of the king, they would have used a different sarcophagus (obviously).'

If, as Anthony theorises, the Queen's Chamber was (in part?) a contingency burial chamber, then it must had a granite sarcophagus (to repeat Anthony's assertion: "The burial chamber was built around the sarcohpagus".

Apart from rather dubious Arab (?) tale, there is not a shred of evidence that the Queen's Chamber ever had a sarcophagus.
