Neil Anderson requests pictures of a Harper Electric player piano.
We have one and would be happy to take pictures of it if it would help.
It is not restored yet, so I can't comment on operation, except to say
that they have horizontal valves which require great care in setting
up.  We do have the original motor, but have not checked whether or not
it is a 12-volt one.  The action was made by Kuhl & Klatt in Germany.
