Hello Jody, Here in the Pianola Museum we have four manuscripts
by J. C. Bunge of his arrangements for the Aeolian Pipe Organ.
We found these in his house in Switzerland where he also had an
Aeolian Pipe Organ. We hope we can find copies of these rolls
(116-note):

1459 Salome (Strauss)
1460 Symphony 4 (Mahler)
1461 Salome (Strauss)
1462 Pelleas & Melisande (Debussy)

Can anyone help us?
