Thanks for the information Antoni.
The website of the link explains the current organ is a replica built in 1995 (see the text in German) in the original organ case. Still, an incredible sound.
(Text from another website: "In 1995, a completely new instrument was made by Jean-Loup Boisseau et Bertrand Cattiaux, aiming to reconstruct (again) the creation of Robert Clicquot and the additions of Louis-Alexander and Francois-Henri Clicquot.").
Listen to this demonstration by one of my favourite organists, Michel Chapuis. The video quality is horrible but the sound is OK.

If that organ could be sampled...
