In 2016 bouwde N.P. Mander een nieuw mechanisch sleepladen-orgel voor de Chapel of Christ the Redeemer, Culham House in Aston (Berkshire).
Open Diapason 8
Stopped Diapason 8
Chimney Flute 4
Twelfth 2 2/3
Tierce 1 3/5
All stops with exception of the Open Diapason and Principal are divided between tenor b and
Manual: GG, AA C-a3, 60 notes
Pedal: C-f1 30 notes.
The bottom C# has a split key so that both AA and C# can be played.
Keys, pedals and drawstop action are all fully mechanical, the switching on and off of the
nightingale, bear and cymbelstern are done pneumatically.
Drum or Thunder pedal
This plays the bottom 6 notes of the Bourdon (when drawn) adding notes progressively as the
pedal is depressed.
This employs the traditional construction for a cymbelstern, with small clock bells, but is
believed to be the only one in the UK which is driven in the traditional way by wind, rather
than electric motor.
Worked by the usual inverted pipes in liquid, but based on an 17th century Italian model,
which is far more compact than the usual nightingales.
The bear is made up of two elements. When pressing the stop with an image of a bear
inwards, the special pipe produces a bear-like sound. If the stop is pulled out the gilded bear
appears silently at the top of the case and the bear sound starts again when it is fully forward,
making the sound as long as the stop is held out. The pipe is a largish wooden Regal with a
hole covered by a pallet, which gradually opens, giving a slight crescendo as it sounds. The
motor for moving the bear is a pneumatic piston, all designed and manufactured in the Mander works.
