Greetings from the Mid-West USA:  ... I have always had an interest
reed organs and self playing instruments. [snip] I have also, as a
hobby, restored several player pianos and Ampico reproducers.

A few weeks ago I was given a French Mustel (Paris) harmonium w/player
unit and 70+ rolls. I have never worked on an instrument which uses
pressure instead of vacuum.  This instrument has two motors: one to
supply the pressure to the reed banks and the other (a small
squirrel-cage engine) to supply vacuum for the player.

Are there any printed materials available for restoration/service of an
instrument such as this?  If there are, I would be grateful for any
information [you] may have.

Thanks for your time and advice.

Sincerely,
Tom Gregory, Waukesha,  WI  USA
