The Great 16' & 8' Posthorn were added by R.A Daffer & Son in 1990.
The Great, all Swell divisions, and partial pedal are on Direct-Electric action.
The Choir, Solo, Positiv, Brustwerk & Pedal divisions are on Electro-pneumatic action.
The 64' Bombarde is built down to low A-flat. They are heavily mitered and half length. They were disconnected due to their poor design and ability to hold tuning. They are now digital & the original pipes are still in the organ.

The Pedal 32' Bombarde is full length & wood laid horizontally in the South Triforium.
The Great VI-X Terzzymbel was originally designed to play alongside the Trompette en Chamade, but got later moved to the Great.
The great 16-8-4' reed chorus was built by M.P Moller & voiced by Zajic.
The original builder was E. M. Skinner & Son (1937, Opus 510).
