Hello.  We have a 20-key barrel organ by Molinari & Sons, New York,
which is in dire need of tuning.  I am unable to locate any information
on the order of pitches, and the process in which to tune such a
delightful instrument.  I assume these were tuned to A-435.  I welcome
any advice and information.  I thank you in advance!

 [ the little 20-key diatonic organ may be a new experience.  What is
 [ the recommended procedure for tuning the pipes by ear?  -- Robbie
