Updated by Michael Menne, who has heard or played the organ.
In 1963 the pedal compass was 25 notes. The 13-pipe 16' rank provided the first 13 notes. The remaining notes were derived from pull-downs from the lowest octave of the Great. Also present in 1963 was the Dulciana on the Great, which apparently had disappeared before the 1993 Andover rebuild.
Updated through online information from John Speller. -- The rebuilding by Andover included extending the Pedal compass to 30 notes, adding a Mixture to the Great in place of an already missing Dulciana, clamping on a Nazard, Flautino and Tierce as additions to the Swell, and converting the Swell Pedal from hitchdown to balanced. Apart from the missing Dulciana the original Hook pipework is largely unaltered. Among the original Hook stops the Trumpet and Bell Gamba are particularly fine. The original Hook case has had its facade pipes restenciled.
The original builder was E. & G. G. Hook (1864, Opus338).
Status Note: There 1994.
Rebuild, with additions. Short compass swell enlarged to 56 notes. 13-note pedal enlarged to 30.
