Bob, I am copying this to the rolls list because there might be some
more general interest or insights.  Hope you don't mind.

I saw your posting about German organs, and hope you might have collected
some information about French organs as well.

In your organ research, have you come across anything about the Gavioli
"Harmoniflute"?  I have an 8-tune 38 note barrel organ I purchased from
Larry Karp.  It is a "Harmoniflute a Trombone" organ made by Gavioli in
about 1861.  I am sure of the date, because when the organ was restored
in the 1980s, the air reservoir was found lined with a Paris newspaper
from 1861!

The most interesting part is the base (trombone) pipe, which is pear shaped
and contains the 3 lowest base reeds (all in the same pipe, with segmented
resonator).  In other Gavioli literature, this is called a "Uniflute".
[accents on the u omitted] The other pipes are all standard stopped flutes.

There were 7 pipes standing in the front of the organ, but those were all
lost and were replaced fairly recently.  I am not sure that they are even
the correct notes, now, so I am looking for any information I can find.
