Is that organ pic for real?

Yep, it's a photo of Rosales Op. 24 at the Mickey Mou---Walt Disney Concert Hall in LA.

Almost all (Atlantic City Convention Hall and the Hill organ at Sydney Town Hall are the only exceptions I'm aware of)) 64' stops are "resultant" stops; that is, the illusion of a 64' sounding stop is produced by sounding a 21 1/3' stop at the same time as a 32' stop.

I was told that the Skinner organ in the Washington National Cathedral has 64' basso diapason pipes, arranged horizontally behind the other pipes. I was told that by the organist David Majors while he was conducting the weekly Sundary afternoon organ recital. I didn't lay eyes on the pipe, though.

Rick, Moises would know for certain, but I believe the 64' Bombarde in the pedal division is electronic on this particular instrument. Or so I've heard.

I'm thinking i would love to have a helicon or some form of tuba made out of a solid block of granite or marble.

As a much easier experiment, you could find an old helicon and encapsulate the entire thing in cast acrylic... leaving only the bell opening and access to the valves, slides, and receiver.

where can one acquire cast acrylic?

Dirty Ernie,aren't tubas heavy enough already?I was taught to never coat out an instrument (especially wooden guitars) because it would dampen vibrations and deaden the sound.
I had the good fortune to spend a year at the Benedictine Monastery at Cullman,Alabama.There was a organ in the chapel with six keyboards and pipes (at least thirty footers) protruding thrugh the ceiling.I was one of twelve trumpets that played in the choir loft with that huge organ.Down on the chapel floor hundreds of monks sang gregorian chant in four part harmony.The acoustics of the chapel were lively and the sound was all pervasive.I'll never forget it.
