In the 50's all production was in Italy. Before the complete transision to Italy some models were partialy made in Italy and completed
in the US. In the late 40's firms such as Excelsior, PANcordion, Iorio & Bell used this practice before their total production was swiched to
Italy in the 50's. These transitional models can be found with the markings --Made In Italy or Made In USA. - Some Excelsior accordions
from this era were actualy marked - Made in Italy - Assembled in USA.
All the US accordion firms from San Francisco, Chicago & New York,NY by the 50's had switched thier total production to Italy for economic
reasons and the fine quality of craftsmanship offered by Italian firms.
In the 50's even the German firm Hohner had because of superior Italian craftsmanship had models of their Morino accordions made
by Excelsior of Italy. Not widely known as Hohner in a marketing ploy labled them as "Made In Germany".
