I bought a Cozatt calliope organ, and I am in the process of
restoring it.  The organ was in working condition when I bought it.
The restoration is going well except for the pipes.  I gave them to
a brass restorer and when I got them back many will not produce a
sound.  I think in the brass polishing process the processor did some
thing to the mechanisms of the pipes.

I do not have a complete under standing as to how they function --
I think the principal is like blowing on the top of a bottle to make
a sound.  Could you please give me a basic understanding as to how the
sound tube is constructed, and what I need to do get the sound back
and how to have the tube tuned if necessary.  Any help you can give me
would be most appreciated.

Thank you,
Selvin Passen, M.D.
