Sadly the console of the Wittenburg organ was closed. You can see this in the new photo. Other photos I now post are of the organ pipes in St Nicholas Church (Lutheran) in Prague and photos of the organ in the Meissen porcelain factory in Meissen. As you can see the pipes are porcelain and I believe that intention is that the complete organ will be moved to one of the Meissen churches.
UPDATE: sorry about the diminished photo sizes. I now realise that the new photos are from thumbnail files not the originals. If any are of specific interest just ask and I will resend.
