In the photos you can see the worn and the broken parts the case, where to carry out restoration work. The damaged parts are carefully restored by gluing the various missing parts with clamps. Afterwards, when the glue has been dried, these newly added pieces are shaped with various tools to fit the shape of the case.
The restoration proceeds with the consolidation of the worn parts: for this work a putty based on glue, previously sifted sawdust and black oxide is used as a wood filler.
The restoration is finished by sanding the putty with fine-grained sandpaper before finally painting and varnishing the case.
