Greetings:  Would anyone have, or know the location, of a catalogue
describing Mustel Concertal rolls?

Would these rolls have the same scaling as Aeolian reed organ rolls?
(The Mustel rolls seem to have the same paper width as standard
88-note rolls, only using 61 notes.)

I will be shortly starting a restoration of a Mustel Concertal and
have approximately 73 rolls for the player.

Thanks in advance for any information available.
