A G. Galleazzi 46
button and 28 bass chromatic (B-System) accordion made in San Francisco.
Everything, except for the cloth under the grill, was made at least 100
years ago, and the accordion is still playable.
(The first accordion, the 100 years
old Maestro Anthony Galla-Rini played was a Galleazzi three-row
chromatic with 32 buttons on the left hand and a lever for minor and 7th
chords.)
