ich habe zumindest unter Ricercare folgende Infos gefunden:
Zitat
GUADAGNINI, FRANCESCO
Son and pupil of Antonio. Worked at Turin, 1889-1935. Particularly clever craftsman.
Modelling somewhat similar to that of Joannes Baptista (2). Varnish, of flaming reddish hue, claimed to be identical with that used by predecessors, only necessitating age to give it the same mellow appearance. Violins with an assemblage of real niceties. Tonal quality highly satisfactory and bespeaks splendid future enhancement. Known for magnificent guitars.
