10237 The Tower of Orthanc: It's almost confirmed

That's all I have to offer you ... A reference: 10237 The Tower of Orthanc, and an image: The one in the white frame above.

On this image that comes from motayan's flickr gallery, the tower itself has been blurred, but we can clearly distinguish the dimensions indicated in inches, which when converted to cm give us a high building of 73 cm and a base with a diameter of 21 cm.  

We can see the edge of the logo "Confidential"usual at LEGO and this visual therefore seems to come from a document that is not intended for the general public (the p that we see is the last letter of GROUP).

If all this is not a fake, with such measurements, we will be entitled to a set of type UCS, Modular, Collector, call it what you want, but it will be very, very heavy ...

Edit of January 06, 2013: GRogall, generally well informed, confirms without further precision the existence of the set 10237 The Tower of Orthanc.
