Another Aeolian Pipe Organ which is still in its original location is
Irenee du Pont's opus 1755 in Varadero Province, Cuba.  The mansion
Xanadu is now the centrepiece of a luxurious "foreigners only" resort,
functioning as an hotel and restaurant.  The organ is mentioned in the
resort's publicity material.  I had heard that the organ had been
restored, but the photograph of the console on the first webpage below
seems to show many missing ivories.  Incidentally, the console is more
like a Skinner design than most of the Aeolians which I have seen.
