It is difficult to show in photographs the ingenuity of Nick’s solutions to the problems. In this photograph one can see that the impost is now straight, upright and secure, though it still carries the same heavy weight. There is still a separate support structure, to which all the old parts of the case are fixed, as well as carrying the wind chests and mechanism. The new organ was based on the c1704 Harris organ at St Botolph Aldgate, one of the earliest to have a support structure separate from the casework. As organ builders gradually discovered there are advantages to managing the project if the mechanism can be assembled separately from the casework.
