In my opinion, the two best ongoing discussions on "band organs"
are the British "fairgrounds organ" web sites:
 
  iMOD (independent Mechanical Organ Discussions) --
  For All Fairground, Street and Dance Organ Enthusiasts Worldwide
  http://organ.10.forumer.com/ 
 
  Mechanical Organs Forum [MOF] -- Fair Organs, Band Organs,
  Street Organs, Dance Organs, etc.
  http://www.mechanicalorgans.org/ 
 
iMOD messages can be read without registration.  MOF requires
registration to read most items.  Both forums require registration
to post and are moderated.  Registration is free.
