Christian Greinacher is looking for details of the small organ
pipe within a singing bird.  I can probably supply a sketch with
dimensions if it would help.

I am a restorer of singing bird boxes such as Rochat, Bruguier and
the going barrel type of Bontems and his followers.  I have had to
make replacement cams, bellows and whistles over the years.  Email
me and I will do my best to help.
