Re Angelo Rulli's request in 000108 MMDigest.  According to Bowers'
Encyclopedia, page 766, there were at least four types of Mignon
organs: 22 notes/22 reeds, 22 notes/44 reeds (the most popular model),
32 notes/64 reeds, and the "Harmonieux" model with 40 notes and
120 reeds, so there is one model with a greater compass than the
32-note type.

Technically, all the models were the same, and the spacing of the
notes was identical.  I have included a drawing of the 22-note model.
Early models had small bellows as pneumatics; the later models
(from 1904) had a pneumatic system with membranes.  Music can still
be ordered: Mr. van der Vlugt, in Tilburg, Netherlands, still makes
the music rolls.  He has no e-mail, but I can forward messages to him.
