In this way they managed to transport the painting to the laboratories of Venaria. 
After the restorers cleaned up behind the painting.
They repaired the tears of the canvas by inserting small pieces of canvas behind the painting.

Abstract of the intervention:

 

The portrait of Charles III It was in a poor state of preservation. The painting has been restored together with other works from the Castle of Racconigi (property of the Castle of Racconigi, Royal Residences of Savoy - Regional Directorate of National Museums Piedmont). The project included a first phase of structural consolidation, in view of the exhibition during the visit of the Reggia di Venaria, and a second phase dedicated to aesthetic restoration and in-depth analysis of conservation events. Thanks to the present restoration, the ancient inscription has been made visible at the height of the sovereign's feet.

Restoration

The intervention began with the velinatura to stop the defects of adhesion of the pictorial film in view of the transfer from the Castle of Racconigi to the laboratories of the Restoration Center. We proceeded with the disassembly of the support, the reinforcement of the support structures and the cleaning of the incoherent deposits by micro-suction of the verso and dusting of the recto. Subsequently, the deformations of the textile support were resolved, the surface was consolidated with adhesive and controlled contribution of pressure and heat and the lacerations of the canvas were compensated. The lining was performed only for the works that had strong depolymerization of the original supports, for all the others we proceeded to the application of strips of canvas perimeter reinforcement. Finally, the re-tensioning and application of the flattened and restored labels on the back of the canvas were carried out.
During the first phase of the intervention, a general intonation of the gaps with watercolor colors was carried out in such a way as to lower the visual disturbance in view of the exposure in the Palace. In agreement with the management of the works, the gaps were stuccoed and tuned to watercolor with temporary additions to be concluded and perfected in the second phase of the restoration. Finally, a light protective was applied. 

The frame has been subjected to a biocidal treatment with permethrin application, consolidation, cleaning and structural rehabilitation with the addition of reinforcement elements. The missing portions of wood were compensated with epoxy resin and the gaps were plastered and then intoned with watercolor colors. Finally, a protective layer has been added with a UV filter.
