Hi, I have a 6-airs music box, presumed Victorian.  I am a clock
collector so don't have any knowledge of these wonderful devices.
What I need is a schematic of the movement, or detailed drawings,
as I have the tune selector mechanism missing, then I can manufacture
one myself.  I think it works on moving the main cylinder backwards
and forwards.

Can you help, or do you have any ideas where the information might
be obtained?

Many thanks,
