Pedal Division

Pedal The Pedal division is an interesting part of the organ. While the console may offer the organist a dozen stop knobs for the Pedal, usually the division borrows pipes from other divisions, and is made up of extensions of other ranks of pipes in the organ. On most organs, the Pedal ranks can only be played on the pedal board. Playing the pedal is not easy and is what separates the "men from the boys" so to speak in the organist world.

In the back of left chamber are two of the Pedal division ranks. The wood pipes are of the 16' Bourdon rank, and the metal pipes seen at the bottom are of the 16' Principal rank.
Pedal Not all Pedal division ranks have gigantic pipes (though most do). Mounted on the black platform are the three ranks of pipes. The first two sets are the II Mixture, and the back set (taller pipes) are the higher pitched pipes of the 16' Principal rank.

Behind the 16' Bourdon rank are the largest pipes of the 16' Principal rank. Due to height limitations, the longest pipes have been mitered in order to fit in the space. The tuning slides on the end of these pipes can be seen. Small springs keep the slides tight on the pipe so they do not move.
Pedal Here's another look a the 16' Bourdon pipes. Note the mitered pipes on top peaking over the smaller pipes. 
Pedal Back in the corner is the largest pipe of the 16' Principal rank (pitch CCC). The sides on either side of the pipe help direct the sound forward. Each pipe was refurbished as necessary by Muller during the organ rebuild.
Pedal In the rear of the right chamber are probably the most powerful pipes of the Pedal division, the 16' Open Wood Flute rank. These pipes originally came from an E.M. Skinner organ (opus 264) which puts their construction date around 1916! Skinner was known for making larger organs so the voicing of these pipes, combined with the 5" of wind pressure, is more typical of a romantically voiced organ.
Pedal On the left is the largest pipe of the 16' Open Wood Flute (pitch CCC). These big blocks of wood require a substantial amount of air in order to get them to reach their full sound potential. Often they have their own offset wind reservoir to ensure they have enough air.
Pedal Here's a closer look at the markings on this rank of pipes. As noted above, "264" is the opus number from which this rank of pipes came from. According to Scott Hayes of Muller Pipe Organs, this rank is from an E.M. Skinner organ. A little internet searching reveals that E.M. Skinner opus 264 was installed in First Church of Christ, Scientist in South Bend, IN.
Often Pedal stops are extensions of other ranks in the organ. On this organ, the 12 notes of the 16' Trombone rank are an extension of the 8' Tromba rank in the Great division. On the left are the 12 pipes of the rank. On the right is the boot of the biggest pipe. W.P. 5" translates to "wind pressure 5", CCC represents the pitch, and the diamond logo on the right is of the A.R. Schopps company which supplies pipes and other organ parts to organ builders.
