Built in 1970 to a design by John Norman, case by Herbert Norman: Gt: 8, 8, 4, 4, 2; Sw: 8, 8, 4, II, 16, 8, Oct.; Ped: 16, 8, 8, 4, 16. The direct electric action enabled the manual 4-foots and 2-foots to be derived below middle C from appropriate 8-foots, but the pedal Sub Bass 16 was independent, and the Pedal Principal/Fifteenth rank (8-foot and 4-foot) independent of the Great diapasons. The Swell Viola 8 has its own bass (stopped quintadenas). The Swell Tremulant has never worked properly as it was overpowered by the effect of a Schwimmer regulator which keeps the wind perfectly steady.
Because the bright tone of the instrument was overpowering in the chancel, while not carrying adequately to the nave, the organ was extended into the Nave in 1995 by Hill Norman & Beard (shortly before the firm's demise) with the Great chorus placed in a double case in the arch near the lectern, and the console moved to the opposite side of the chancel. The new Great Dulciana is of full compass, using twelve former Open Diapason pipes in the front of the Chancel case. The Great Dulcet 4, with 24 notes derived from the Dulciana, has an independent Gemshorn treble. Diapason 8ft in the Nave gives a strong lead to congregational singing. The Nave 4ft and 2ft borrow 24 notes from it below middle C, as in the original design, but the Twelfth is independent, voiced to blend with the Chancel flutes. The new Pedal Open Diapason 16 is an electronic unit buried deep in the organ chamber.
Radiating/concave pedals. Stop tabs. Balanced swell. Usual couplers. Nave Great on Great/Swell; when on the Swell, it is affected by the Swell Octave coupler, so the Nave Great stops can be coupled back to the Great at octave pitch. Compass: 56/32. 6 general and 4 Great/Pedal thumb/toe pistons, and 4 Swell thumb-pistons. Thumb/toe-pistons to some couplers. Lockable setter piston.
The redesign has been extremely successful, and the organ has become an excellent accompanying instrument for church services, and a very flexible instrument for recitals.
