North Italian (Bologna?) square piano ca.1790
This piano has missing dampers and has a Bolognese (if I may call it!) simple Prellmechanik.
The reason I call it Bolognese is because such an action which is simple Prellmechanik used also in Germany and elsewhere is made in this special way mostly made in North Italy and specifically in Bologna like those of Luigi Barbier.
This one is probably not by Barbier (apart from some differences from furniture) it does not have the usual Barbieri under dampers but has missing normal dampers which raise by pieces of wood or metal that connect the key ends to the dampers.
After some documentation and conservation this special piano will be restored in the workshop.
