After a search here in the forum, this model is physically similar to that of the Juliett Pianola and the Meazzi Accordietta Gigante, although there is no indication of the manufacturer.
If “La Sopranina” has the sound similar to Clavietta, as Alan informs on the topic about Juliett Pianola, I am interested in acquiring, since I really like this type of sound and, unfortunately, I still can not get the Borel model.
However, would the fact that this model be called “La Sopranina” inform that it is a soprano model? I mean, would it sound like an octave higher?
