From Castel Fidardo Italy Manufactured by Beltuna and made in Castel Fidardo Italy. It has 96 (deep Helikon bass) and 3 treble reeds with musette tuning.(1998)
120 bass piano accordion with Free Bass. This turns 4 rows of the left hand buttons into single notes, turning the left hand into a four row continental chromatic accordion. This is used especially to play classical music.
4 row C system 120 bass button accordion manufactured by the French Maugein company. I tried to convert it to the Reuther uniform keyboard. This necessitated rearranging the reeds and adding a row of reeds so that the first and third rows were the same. Unfortunately the instrument being old was too heavy and too cumbersome and the project was abandoned.
