Hello Marcus and MMDer's,  Have a look on our tune-list for music
books on www.notre-repertoire.com or direct link for 52-key Gasparini:

http://www.leludion.com/ventecartons/index.asp?f=GASPARINI&m=52%20touches%20/%20m%E9canique

Original Gasparini music books are listed with "GSP" tags on "noteurs".
All others are new arrangements.  You can listen to the first 25 seconds
of each tunes by clicking the loudspeaker icon on the left side.
Of course we could provide you a tuning scale.  I hope this helps you.

Best Regards,
Philippe Crasse
Le Ludion, Toulouse
