System: Péguri (unisonoric, multi-part logical)
(Collection Oriwohl, Nr. A-97)
Manufacture: Co. Fratelli Crosio (Italien) around 1960
Around 1925, Charles Péguri also tried to transfer the C fingering to the bandonion. However, he did not go to the trouble of redesigning the entire keyboard mechanism, as was done with Meisel and Praktikal, but only replaced the reedplates on the 142-tone bandonion.
With relatively little effort a bisonoric instrument was transformed into an unisonoric. Thanks to the unchanged case construction, the sound is very close to that of the bisonoric bandonion.
