This beauty was designed/built by John Norris (Tuner Sales Manager, Ext. 141) and Pat Bovenizer (Vice President, Ext. 102) -- approximately 10 years ago. It has only been used a few times: pristine condition.It utilizes an electric air compressor along with pneumatic MIDI control mechanisms, which are tucked inside the lower portion (sealed with a hinged door to high quality magnets; sort of like an upright piano) to blow air over glass bottles for musical purposes.Each bottle has its own MIDI number, and there are 25 bottles (i.e., 25 notes) in all, with a range of about 4 or 5 good octaves.The desired frequency of a given bottle is tuned by adding or subtracting mineral oil (an eyedropper can be useful), and since mineral oil doesn't evaporate, no retuning is necessary. Any MIDI controller or sequencer can be used to control the airflow, and thus, to play the organ.These organs typically sell for a lot of money (much more than I'm asking).
