Hello ! i have this book "Burgmuller - 25 studies" Ref. GXS720180 and
I'm looking for the registration data which come with the book. I asked
to Yamaha Ginza and they don't sell the registration data separately :-(

There is no backup data in the eldisk data base site ...

Does somebody have the registration and would accept to share them with
me ?

thanks a lot in advance for your answer,

best regards from France,
