The Principal pipes are visible in the front of the case. 

The longest 12 pipes are of aluminum.  The shorter pipes in the center of the case are made from an alloy of 70% tin with 30% lead.  The Subbass pipes are of wood and are visible at the sides of the case.  The remaining pipes are inside the case behind swell shutters that the organist can open and close to adjust loudness while playing. 

Each the lowest 12 Subbass pipes plays from 2 valves.  The Gedeckt 16’ stop plays those same pipes at a softer volume by opening only one valve per pipe. 

The Trumpet shallots are slightly tapered, similar to those used by Henry Willis I in England.  The first 17 Trumpet pipes have half-length resonators in order fit inside the case.

The Gemshorn uses narrow scale, bright-sounding pipes.  The Celeste uses broader, rounder-sounding pipes.
