The Identity of X and Q in part 3 of Kryptos

So part 3 of Kryptos reads:

SLOWLY DESPARATLY SLOWLY THE REMAINS OF PASSAGE DEBRIS THAT ENCUMBERED THE LOWER PART OF THE DOORWAY WAS REMOVED WITH TREMBLING HANDS I MADE A TINY BREACH IN THE UPPER LEFT HAND CORNER AND THEN WIDENING THE HOLE A LITTLE I INSERTED THE CANDLE AND PEERED IN THE HOT AIR ESCAPING FROM THE CHAMBER CAUSED THE FLAME TO FLICKER BUT PRESENTLY DETAILS OF THE ROOM WITHIN EMERGED FROM THE MIST X CAN YOU SEE ANYTHING Q?

A fairly pertinent part of Howard Carter’s journal reads:

“There was naturally short suspense for those present who could not see, when Lord Carnarvon said to me `Can you see anything’.”

Here are X and Q:

X = Howard Carter

Q = Lord Carnarvon

p.s.  Q could also stand for “query” which was the telegram convention for a question mark.  This would mean X was a stop.  Not quite as fun as the above but equally possible… (ref: Nelson Ross, 1928)
