She is playing a copy of a guitar by French luthier Lete ca 1830 made by Dutch luthier Martin de Witte. Lete was contemporary with Lacote and Pons.
They used spruce as the base for an outer veneer of some hardwood. It could be Rosewood, Maple, Mahogany.... Generally it was only the back that was veneered but occasionally instruments had veneered sides as well.
This style of building was common in the French school and is an important ingredient in the "French" sound. It is not so commonly found in the other schools and basically not at all in the Viennese (extreamly rare). Fabricatori also seemed to not be so fond of the veneered back but quite often lined the inside of their guitars with paper.
