For years I had thought the the pump organs built pressure when played, But to my surprise I determined that the two exhaust bellows pull a vacuum on the main regulator bellows and wind chest. So I tell people not that the pump organs “Suck”… Everyone seems to get a laugh out of that one.
In the past I had tried taking a video of playing this organ,,, but the frequency response of the camera’s mike was unacceptable. This one is better, but not stellar. Part way through the video I pull 2 stops, the first you can hear, but the second should have added an octave lower on the base notes. Again the frequency response of the mike in the camera is less than desirable. SORRY!

Great!! I still want to come see it in person, the workmanship looks impressive.
