On checking the above two sites it can be seen that there are going to be some substantial alterations and additions. The case is to be split in two - or more likely, two completely new cases are to be made, on either side of the choir.
Two stops are to be added to the Great, three to the Swell, 7 to the pedal, plus a change from a posaune to an ophicliede, and a new solo manual with 12 new stops is to be added.
Estimated cost, £1,000,000.
